Re: [Z_Scale] Re: MTL Switch grinding
- Do we know what the depth on the MTL frog flangeway is? Or the AZL
You can possibly just replace the frogs with the new Proto:87 Stores Z
Frogs, (NO milling machine needed ;) )but the current FW depth on those
is ~0.020" on the code 40 and ~0.027" on the code 55's.
The guard rails are functional, so grinding them back without may also
cause some derailments due to frog vee picking.

It is too soon to say. I know from my contacts with Marklin that the Z line
is part of their long term plans. But it really depends on the new owner
once they are established. The Z line is now under the control of the Trix
team. There are some in Marklin who want to bring it back to the Marklin fold.
We are all waiting for this time of uncertainty to come to an end.
