Tom! Have been discussing brakes again with certain members of the group, and have learned a few things. 1) The Midland DID run non-air foreign cars in the 80s...
Adrian and folks "Mountain" cars are actually mentioned in CMQ 2 on page 3, I have noticed a continuing thread on the braking qualities and procedures as I ...
Tom I suspect that in 1891, the two terms mountain vs. prairie did perhaps mean air vs non-air cars. The six cars of bridge iron were perhaps loaded onto...
Adrian The CM gang will accept and appreciate the assistance. This appears to be one of those sleeper issues, not recognized until we got enough information...
The Midland used the Quick action A.B. system developed by Westinghouse. The earlier system as initiated on the Big Q. was the "Plains" system as noted. I...
AB as early as 1903? Adrian ... From: coosbaylumberco <coosbaylumberco@...> To: ColoradoMidland@yahoogroups.com Sent: Monday, April 9, 2007 5:30:31 AM ...
... Sorry Wm thought you were talking about AB system as developed after WWI. A.B. in your message just means air brake, right? makes sense what you are...
No you are mising the point here. The interior size of the brake pipe was very-very important. For due to friction (Bernouli formulae) of the air on to the air...
... It's actually even more complicated than that. There are a lot of dynamic effects that go on during a reduction (brake application), lap or release. When...

Thanks Bill, this is starting to make more sense now. Can you explain what you mean by the 'braking ratio'? I am beginning to doubt that the speed of release...
A...... Perhaps the air brake saved the Midland. For it permitted 10 car trains to become twenty car trains. The locomotives were certainly strong enough, but...
... I'm not an expert on it by any means but basically it's the amount of force the brakes can exert at full equalization. (full equalization means the maximum...

Adrian... The "Braking Ratio" is that numbre which applies to loaded versus empty cars. How many loads and how many empties in that train? If everything were...
Hi All....Just came accross a Photo of the Model RR in the Town Hall in Buena Vista by Mike Epstein, in the West Mag of the LA Times.....It Promotes a book he...
Hello Group! Though I have been inactive here for some time, if you will allow me to inject a bit of theory into this discussion: I am a railroad locomotive...
Andre The history of the Midland is replete with many stories of boomer engineers quitting after their first trip eastbound down either Hagerman or Ute Pass....
Hi Tom: Good to "see" you again. Having taken the time now to read most of the posts in this thread, it would appear that Bill hit the nail on the head in a...
... Thanks Andre - It happens I've worked with brakes not much newer than we're talking about here. Like you my first suspicion was that the engineer had...

I was a train disatcher for 13 years on the Delaware & Hudson when it was still independent. Tho in the east, much of the road was and is mountainous (by...
Andre I think the early systems were even tougher on the engineer than the 6 series systems. Your evaluation of the crews is right on. Thanks of the further...
Posted on Ebay:brass HALLMARK CM COLORADO MIDLAND 2-8-0. 1988 run. CP! Price is out of my range - I have no idea whether it is reasonable. Question: Is this...
David, I do not seem to find it, do you have the item number? Was it a buy it now? __________________________________________________ Do You Yahoo!? Tired of...
Yes, those are the colors right off our data sheet Daryl Ryder and others researched. It was included in the box. Nice to see CM engines painted right. I like...
Gee. I got a 300 a number of years ago at a local shop for about $150. Within one week of them arriving too. The remainders at that shop sat and sat. The shop...
Save me some time here so I do not have to look thru the books for the answer to this question. A friend found a rod that appears to be a pin from a link and...
Hi Ken; Yes, the Colorado Midland did have link and pin couplers. I am not sure when then switched to knuckle couplers. If you want to see an example of both,...
