    Malcolm, you are dealing with multiple manufacturers, different motors, drive trains, and designs. To think that all locomotives should be like is incorrect.

      Malcolm, you are dealing with multiple manufacturers, different motors,
      drive trains, and designs. To think that all locomotives should be like is
      incorrect. Just because it has a motor and wheels does not grant a product
      automatic similarity. Does a Kia run like a Ferrari? No one assumes they will. So
      why should we assume our model trains will?

      Motor specs alone can be very different. Marklin uses dozens of motors
      which slightly different specs. AZL and MTL both use 8mm motors, but from
      different manufacturers so the specs are different. Gearing and design
      considerations also means that loco classes from the same manufacture may differ. An
      SD40-2 from MTL does not perform like a GP35. The gearing is very different
      since one is 4 axle the other 6.

      What is more valid is to assume like locomotives from the same run will
      perform consistently together. So if you purchase three like locomotives, the
      will perform much the same. Note though, different runs of locos may act
      differently. Why? Many reasons. Minute changed is tolerances, too much oil, or
      not enough... etc can all factor into performance of a loco. An extended
      break-in period can resolve many issues.

      I caution folks from just claiming locos are 'defective'. What may be your
      perception could very well be the design choices the manufacturer made. DCC
      will solve the issue running dissimilar locomotives together. If you do only
      operate DC, run performance test on your locomotives to determine which
      locos run well together. I actually run my AZL SD40-2s with MTL GP35. I found
      this two very different locos run great together!

        Malcolm,
        Your speed mismatch is an excellent example. I would have tried to run it
        with my MTL GP's and if there was nothing visibly wrong with the SD I would
        have probably returned it as defective.
        I suppose the point I was dancing about is that virtually all the loco
        manufacturers contract out the actual manufacture. So how do they accept a
        received product? I'm not sure I want to know the answer.

        Mark

            Rob,

            While I understand your arguments, I don't think they really address Mark's or Malcolm's questions/comments.

            While I have never heard of any manufacturer supplying the sort of information Mark says American Flyer supplied concerning current draw, that would be a very handy piece of info to have.

            Of course it would differ between manufacturers and for different models from the same manufacturer. But it should not differ greatly for the same model by the same manufacturer. If a new GP35 from MTL typically drew 50 to 60 ma at 5 volts, then I would expect something to be wrong if another one drew 80-90 ma at 5 volts. That is simply too large a difference to attribute to different runs. A difference of 50-60 percent in current draw indicates something is wrong.

            The manufacturers of z-scale equipment do an excellent job of producing very good-looking items, and for the most part good-running items. Even if they did not include the expected current draw information, I think it would be a real plus for operation if they did a quick check on current draw at the time of manufacture. It would probably go a long way to head off complaints that a newly purchased engine doesn't seem to work correctly.

            But I would love to have some idea from the manufacturer of what numbers I should anticipate for a properly working engine.

                You also have to consider the motor specs for % or variation in the units manufactured. I think you will find that if you take the part number off the motor in your MTL or AZL engines and go to small motor supplier you will find the data you are looking for. You should also be able to see power &/or torque curves versus RPM.

                I think comparing an American Flyer motor to the ones we use today in Z is like comparing a model T ford to a present day Dodge Caravan.

                  My question isn't so much just accepting a loco, but maintaining them. As an example from the MR review I know a GP-35 running at 200mA is good. Is 250mA still good or is it suggesting maintenance time?
                  The RPM around an oval is a good way to match locos as well as check the performance. Would Malcolm have been concerned about the SD-40 if it were identified that it does 5 RPM when a GP-35 does 7?
                  As for hard numbers, I could publish what I have on GP-7s,9s, F7s (Marklin & MTL) and a Mikado, if anyone is interested.

If a new GP35 from MTL typically drew 50 to 60 ma at 5 volts, then I would expect something to be wrong if another one drew 80-90 ma at 5 volts. That is simply too large a difference to attribute to different runs. A difference of 50-60 percent in current draw indicates something is wrong.

Even if they did not include the expected current draw information, I think it would be a real plus for operation if they did a quick check on current draw at the time of manufacture. It would probably go a long way to head off complaints that a newly purchased engine doesn't seem to work correctly.

                        Mark,
                        I went back to the beginning and reread your question. I think I get it now. I'm not aware of any set standard to measure AZL or MTL loco performance. No set rules, the bottom line I guess is to compare several like locos and notice what the average speed of each is.

                        A timed circle will certainly tell you which loco is a slow poke. From there it is likely a matter of tweaking the slow loco to get it to speed up. Not always possible I suppose due to manufacturing idiosyncrasies and care of assembly, (the human factor) perhaps being just a tad off, but generally speaking each loco should perform very close to the operational characteristics of other locos.

                        Ever heard of the advice to not buy a car built on Monday or Friday?
                        Same may be true of locos or anything else for that matter.

                              Loren,
                              I'm a preventive maintenance sort of guy. I've started running more regularly these days and considering when its time to do a PM on a loco. Marklin says oil every 20 hrs. but that's about it. In my experience with American Flyer engines they basically specified a upper current limit for a running engine, and a distance it should travel in a minute, under specific conditions. The 1st measurement would tell me if its time to clean the motor, replace brushes, etc. and the 2nd usually meant its time to relubricate. I posted a link to examples in another message. I want to do something similar in the way of quantitative measurements for my Z.
                              I generally run a speed and current test on everything I aquire. So I'm wondering how much of a current increase or a slow down (or some other measurement I haven't thought of) would indicate that maintenance would be required.
                              The side comments with Malcolm are: wouldn't be nice if manufacturers provided some of this info as it would make it easier to do maintenance, would help set performance expectations and provide a consistent basis to answer the original question.

                              BTW: I always spend too much time working on my engines...of course I wash the windows inside and out.

                                    Mark,
                                    I can't speak for anyone else, but from attending many a train show and
                                    observing others I have come to the conclusion that preventive maintenance
                                    is the best thing just prior to a show or for a home running session where
                                    you want and need your fleet of locos to run flawlessly and without any sort
                                    of hick up other than the occasional derail which happens to all of us from
                                    time to time.

                                    On MTL locos, the preventative maintenance prior to a show consists mainly
                                    of removing the truck side frames, checking for lint and foreign material on
                                    the gears, maybe blowing any particles out of the wheel sets, and a tiny
                                    drop of oil on the manufacturer's suggested points. That and cleaning the
                                    wheels is about all you must do routinely to insure consistent performance.
                                    The entire process takes only a few minutes and is fairly simple and pain
                                    free. AZL locos are similar with minor differences.

                                    Dirt is the Achilles tendon of Z scale operation. Start with excellent
                                    track work, regular track cleaning and loco maintenance and you have the
                                    formula for 'good times'.

                                    Personally I don't think any sort of written parameters are needed or
                                    necessary. The whole process is so simple and quick to perform.

                                    Just a casual runner's 2 1/2 cents worth.

                                    Loren

                                      One additional comment regarding loco performance. Loco performance
                                      depends partly on how it was assembled and with what care, and also the
                                      actual parts used. Once a couple of years ago, MTL's machine for making the
                                      F7 wheel sets became a bit worn and the resulting wheel sets had a slight
                                      wobble from some factor I am not well versed on. The problem came to light
                                      in part when one of my customers complained of F7 wobble. Upon
                                      investigating the issue, the worn tooling was discovered. Upon correction
                                      of the faulty tool the problem was completely eliminated and all campers
                                      went to bed happy under the stars that night.

                                      I think Rob Kluz thoroughly explained why some locos just don't sync
                                      together easily, differing gear ratios taken into consideration.

                                      I bought one of the first AZL UP GP7s that was not really ready for prime
                                      time and was released prior to the regular release. One would have expected
                                      it to perhaps perform less than ideally because of its early production and
                                      not having everything just exactly right.
                                      Low and behold, due to it being hand assembled by a person who really took
                                      pains to insure the best, my particular loco ran like a scared rabbit.
                                      Nothing from AZL has ever run quite that good. It walks away from other
                                      GP7s I've had so I call it my little 'streak'

                                      This is not to say the other AZL locos have not run well right out of the
                                      box after a little break in time, but this particular loco seemed to be in a
                                      class all its own. I know that is an exception to the rule.......but you
                                      won't hear me complaining about its speed.

                                      Nice little choo choo.

                                        There is a great deal of difference between an American Flyer or Lionel engine with open frame motor with weight and one of our little Z scale jobs. From working in a hobby shop in early 80's never saw one with cruddy wheels like we do in Z. Being over oiled was never a problem with the heavy weights but it certainly is in N-scale and particularly is Z.

                                        My preshow check is like Loren to be sure the trucks are clean and have nothing in them. If they look dry then a tiny drop of oil otherwise no oil. I sometimes use a bit of teflon powder if an engine is having trouble out of the box but usually it justs need a tweak on the truck and chassis screws. I have never seen warn out wipers in Z like I have in American Flyer and Lionel. The American Flyer and Lionel stuff I was working on was 40 to 55 years old and our Z stuff just hasn't reached that age yet.

                                        My basic approach is if it is clean and running leave it alone. If it is sick fix it. And if it is Marklin and old then make sure you run it monthly so it does not freeze up, but I usually clean a new Marklin engine and re lubricate it with Labelle right out of the box so I have avoided the dreaded harden oil syndrome for most of the engines in my Nn3 & Z collection of Marklin steamers.

                                        Working on David George's fleet of engines the only maintenance I have had to do was due to crude on wheels cat hair in things including axle cones of his rolling stock and broken couplers. The only reason the engines did not run on the track was no power getting through to the motor. Once cleaned they were off and running again. At shows I run a track cleaning car behind the engine on my train consists and I have found metal wheels are a great way to add weight to your cars and they do not collect the crude the Delrin wheels do. No cruddy delrin wheels no crude on diesel wheels either. Then I clean the roller on the track cleaner between shows also.

                                          I don't do any benchmark on any of my locos. But without any measurement I immediately know when of my loco runs smoothly or on the opposite jerky.
                                           
                                          -For example I've a batch of the first released AZL SD70s, those who run very slowly. I've read here and there that once put appart and reassembled again they run faster and with a lower current drive. Maybe. But as these run very smoothly and as I'm not looking for high speeds I don't need any intervention on these, as furthermore I don't experience any overheat on them nor on the power supply system.
                                           
                                          -I had once a stuck GP35, I guess after it swallowed a grain of ballast or any other rubbish. I sent it to my local hobby store for overhauling. After they charged me of the equivalent of $20 I recovered a loco that ran jerkily.... I just unscrewed a little bit the 4 screws holding half chassis together and everything came back fine (that lets me telling myself the next time such an event occurs I'll fix it myself....).

                                          Exactly. Manufacturer data would be nice. But also how do other people here bench mark their locos?

Something provided by the manufacturer that tells the standard performance characteristics of a locomotive. That way, you can compare your loc to the bench marks to see if it is running properly.
