Just when you thought you seen it all:

for some reason, the NS bridge with the plastic ties that burnt down a few weeks ago, and took four locos with it, comes to my mind.....

now the model railroad companies will have to come up with a material that looks like plastic . hmmmm.

Otto had an Article in Trains about bridges made out of polystrene , well polystrene covered in concrete .
