... snipped ... Do modern trains operate on cruise control? From my days in Colorado, I always noted that the trains generally slowed down when going up ...
It's extremely difficult on a model to manually realistically simulate the prototypical slowing on grades, because the huge inertia of long heavy trains makes...
leaving aside for the moment unit trains, which do operate on cruise control when going through flood loaders, you are quite right. However there is something...
... snipped ... snipped Andy, You are correct on that issue, point taken and thanks for the reality check. However, it would be nice if there was a way that...
Ken, Thanks for the informative reply. I am in the process of developing a small waterfront yard in N-scale. It's really an industrial switching layout with...
... If the decoder's processor has enough spare cycles, I can imagine having it integrate the instantaneous BEMF over an appropriate interval to detect a...
... There are several companies that make back-emf decoders that will fit in N scale locos. My favorite back-emf decoders are Zimo, which I've found to have...
The July issue of Model Railroader arrived yesterday and, as usual, track plans catch my eye first. Tom Danneman's Montana Rail Link is a very interesting...
Thanks Ken, The KATO NW2 loco is "DCC friendly" and Digitrax makes a "drop-in" decoder -- no mention of bemf capability so I'll assume it has none. That being...
... running ... the ramp ... Nothing that prevents the whole train from being pulled foward, delayed uncouple, shove the train back, and the loco is freed up...
... While BEMF can be useful, I'm going to take a devil's advocate postion. I've been doing DCC for 14 years, much of that time with Digitrax BEMF decoders....
Joe, Interesting and informative. One of the neat things about these lists is the ability to gather a lot of operational experiences, to help find the best...
I'd agree strongly with Joe on the multiple BEMF locos "fighting", but for single locos, especially switchers I really like BEMF, especially Zimo, as Ken Rice...
My personal Devil's position is twofold ;) 1 I've never read anywhere that the top priority of model railroading is to be the cheapest model possible,...
... This relates to my wish for a feature I have not yet seen on any DCC throttle - acceleration and braking operation like a real locomotive. I'm aware that...

Joe, I think that it important to point out that you run diesels. Modern plastic diesels have excellent slow speed characteristics and electrical pick up....
... If the decorder's processor has to digitally compute the motor on pulse width to achieve a desired speed, then it is a "simple" matter to program it to use...
Regarding BEMF speed control instability when multiple engines are consisted: Doesn't DCC give you the ability to MU slave several locomotives together?...
All I have is a recollection of a hump yard at the Franklin Institute (Philadelphia, PA) back in the late 60's (I was around 10). The HO layout has since been...
