Leo et al...That's the problem that all us old guys have anymore...Aiin't nobody who knows NOTHIN" about how it used to be and there's nobody left to ask.
I don't really consider myself old, but I've got 1956 seniority and a lot of memories back to the early 40's which I can document as being correct...Is there anybody on here who predates that????

Notice also states one copy is to be placed in each power car under glass with out fail. I sure wish some of the old Aurora/Eola switchman I worked with were still around to tell us why some power cars ended up on the east end of these small consists Leo Phillipp --- In CBQ@yahoogroups.com, "Charlie Vlk" wrote: > > I'm leaving the material below attached so this can be put into previous > message context: > > > > I recall a discussion at one of the annual meets (with the late Bat > Masterson???) about the transition on the E7s not being set up as well for > acceleration of the commuter trains.
