A friend of mine at work is building JV Model's 36" curved trestle bridge, better him then me.....lol after spending hours looking at Alan Kelleher's videos of Greatest Model train layouts. I noticed every bridge or trestle had what I've always known as bridge track. You know the inner safety rails. So he tells me that Walthers list Bridge track and Trestle track separately. Can anyone tell me the difference?
Thanks
Depending on the railroad, some companies only placed guard rail on certain types of bridges, certain bridges, certain bridges with a certain degree of curve and some even only on "high speed" bridges... it just depended. Add into this that each companies internal guidelines for this changed during WWII (due to steel shortages) and it REALLY gets interesting... RMC has a great article on this (I think April '07).

Some bridges actually had RE-RAILERS and other contraptions on them... was very interesting around the 1900-1930's what all went on bridges. The railroads were trying to prevent one care from derailing and taking the whole BRIDGE with it.... trains were CHEAP compared to the cost of trashing a bridge, even if only the decking/rail, which could put it out of commision for weeks to months!
P.S. Check out some of the cyclopedia books from 1900-1930...crazy stuff on bridge railing, guard timbers, re-railers, etc.
