pretty common philosophy, pulling a train more reliable than pushing one. prototype and model.

also unpowered unit is normally lighter, more issue pushing lightweight car from end of train

(there are other prototype reasons also)

some of these are also geared higher, so might need the extra motive power.

should result in less amperage draw but significantly lowered top speed.

Rapido has recently announced the New Haven (and others) Roger Williams trainset.  The NH purchased them in 1956 and consisted of front and rear RDC cab units and several intermediate RDC's.

the Rapido set will have front and rear powered cab units and a single intermediate unpowered RDC.

will installation and operation be as simple as installing an LM in both powered units then speed-matching them?

thanks

Does your O Scale F7 draw so much current that the G scale board is required?

New HC-3 starter kit up and running with an LM-4G-S installed into an Atlas O scale F7. No real issues other than time to download / transfer files.

My question(s) pertain(s) to running trains - my understanding is that the programable Acceleration Time and Deceleration Time are similar to the momentum function on a straight DC layout. What do the times represent? Is that time from 100% throttle to 0% / 0% to 100% throttle or is it something different? I guess I was expecting more of a change when going from zero to max in that adjustment. So much so I was using Load to increase momentum.

Which leads me to question #2 - Is there a way to set the Load of a locomotive and save it? I was adjusting mine to increase momentum as well as timing the notch changes. Was disappointed to learn (unless I'm missing something) that setting isn't saved anywhere so it has to be entered each running session.

Other than that, great way to run trains!
