CASE STUDIES OF TIMBER BRIDGES' PROBLEMS CAUSED BY UNIT TRAINS

At a threshold of up to 20 million gross tons, properly built and maintained wooden bridges are able to withstand unit train traffic; beyond that point the amount and severity of damage increases rapidly. The regular vibrations produced by uniform cars uniformly loaded has damaged stringers, pile caps, bents, and the piles themselves. Stepped up inspections are essential to assure safe, economical operation and possible steps to repair and resist damage are described.
