I don't want to drift too far off subject, but. . 

In ~1964 I had the fortune of riding Santa Fe from KC to Chicago on the 
overnight Chicagoan(?).  We had A-B-B-B-A F-7s and about 20 cars.  When we came 
off the Mississippi River Bridge and cleared the curve from the bridge, the 
entire train of lightweight cars, mostly Budds, suddenly lunged forward enough 
as it picked up speed that I was pushed back in my seat, there was no sign of 
slack running out.  Later in the trip I asked what could have caused this, and 
it was suggested that all 5 units had transitioned at the same instant.  Also, 
remember that F-2s and FT-s had "manual" transition, and even to their demise, 
it was cautioned on RI to have them lead newer automatic-transition units, as 
they could get burned out if they were trailing.   Replicating that in the 
model venue could be a real trick.

  The speed is what controls whether or not the engine goes through transition. 
Usually they are set at about 24-26 mph for the engine to transition. The 
reason they are set in that range is so a consist doesn't transition all at the 
same time. Bad for the engines and bad for the train if you're on a grade and 
all transition at the same time. :*(

here the engine throttle up all the way with no transition and as soon as the 
crew got her moving the engineer would throttle down to iddle "with no 
transition" and coast through the switch, and they were working that engine 
hard...
