MTH HO Canadian Pacific ALCO FA-1 A & B units
Posted by Canadoug on Tuesday, April 10, 2018 9:34 AM

Hi everyone, I would appreciate some advice on the following:

I very recently purchased a pair of MTH HO scale Canadian Pacific ALCO FA-1 A & B units, which I would like to modify as only the B unit is Protosound fitted. Has anyone got a tip on how to remove the bodyshells?  I have undone the 4 chassis and two coupler screws and expanded the sides which I've held open with credit cards but the body seems to be firmly held at each end of the locos.

My plan is to swap the sound decoder and speaker into the A unit; is it possible to run both units with sound from the one decoder, I've never heard of this being done?

Regards

Hello All,

I know I can't vouch for everyone, but I personally am unable to find any sort of schematic on this locomotive anywhere, and without some sort of visual I have no idea how to help in dismounting the shells. By your description it sounds like there is still something keeping the shell attached to the chassis at the ends, meaning either some sort of screw is not undone, the shell is clipped in by the ends, or there is some sort of adhiesive keeping the shell in place. Without any sort of visual I can't help more, but I'm sure one of the many users here might be able to think of something else.

 

As for the DCC, I'm not entirely sure. I've done some messing around with DCC, and do know that two locomotives can be RUN by one decoder, in the case that there is no sort of sound. With sound I can't say I have any idea. The main problem with running with only one decoder is current draw, as most decoders can handle one loco, but usually not two unless it's a good decoder. There was a forum similar to this awhile back, http://cs.trains.com/mrr/f/744/t/262085.aspx, but it does not specify whether it is utilizing a sound decoder, and is rather short; Though I imagine the properties of a sound decoder are similar to a standard decoder. 

Do wish you the best of luck,

MM
