Re: [CBQ] BURLINGTON BRIDGE

[James Koretsky <jameskoretsky@comcast.net>]

Bill,

Ballasting a bridge means that the track is just part of the right of 
way and not fixed to the actual bridge itself. You can maintain a much 
better alignment through the bridge and in theory maintain track speed. 
I'm sure there's more to it from an Engineering point of view, but if 
you can ballast a bridge, you'll get a better ride across the bridge.

Regards

James
