QUOTE: Originally posted by edblysard For the most part, engineers try hard to ease or eliminate curves on steep grades, but sometimes it cant be avoided. A gentle or wide radi curve makes little difference to most trains, its the sharp, or tight radius cruves that cause problems. Engineers avoid this combination whenever possible. Take note of Horseshoe curve, and Tehachapi loop, both designed to gain elevation in as little space as possible, but both have releative gentle curves. You see trains stopped in the sideing at Tehachapi all the time. Where a sharp curve on grade cant be avoided, and the curve is severe enough to affect operation beyond what the grade itself causes, then that curve becomes the ruling grade.

I saw a train that consisted entirely of truck trailers that were NOT (as best I could see -- I'm fairly certain) on train cars. I believe they sat right on sets of train wheels; the back end of one trailer and the front of the next one shared one of these sets of wheels. I know train cars have their own brakes. Do these things have brakes? I hope so, but I couldn't see anything connecting the sets of wheels! --Nora

QUOTE: Originally posted by jamesedwbradley Didn't see this point raised - an engine, or group of engines, whether or not coupled to cars, is a TRAIN - IF, and ONLY IF, markers are displayed. If no markers, it's just engine(s), 'light', or pulling a 'cut' or 'draft' of cars, not a 'train' for dispatching purposes, and could only function within yard limits under most rulebooks. With the advent of track warrants I think things have loosened up a little bit, but I believe the 'train' definition holds, and the warrants are still issued to a 'train', the engine or engine/cars being authorized as a train to 'run extra'. Any confirmation/correction from the active railroaders out there? James E. Bradley Hawk Mountain Chapter N.R.H.S.

QUOTE: Originally posted by Mookie Thanx Ed - I was questioning what a marker was when you answered it for me. Reading my mind again, I guess. Wish you would quit that! Nora - I got all excited on the forum one day flapping my arms and hooting because I found the bell. If you are in a car, it will be about eye level - depending on which side it and you are on. BNSF runs with theirs on the left - just behind the first set of wheels and they are a nice size, so you can see them! Jen
