I have an older F7A that I am about to re-power.
I would like to place a Sound Decoder and speaker(s) in the 'B' unit.
Where can I find a set of connectors to join the two units.
I converted a Spectrum loco to DCC and there were two connectors between loco and tender = I need something similar - any ideas?  Thank you.

How do I compute the angle to 'bank' a track with a radius of 22 inches and a 2% grade?

We have a Baldwin 2-8-0 Consolidation Item 11411 and would like to install DCC with sound.
Any suggestions?

I plan to convert Gordon and James to DCC.
In the meantime I would like to couple the cars from the Gordon and James sets to work with DCC Engines that have E-Z Mate Mark II Couplers.
Would the BAC 78035 be the correct coupler for Annie and Clarabel and the other cars?
