This timber trestle caught fire in the early 1990's. The structure required replacement due to subsequent deterioration over time, coupled with ever increasing rail demands. Canadian National (CN) had to ensure minimal rail disruptions during replacement of this section of mainline, with upwards of 40 trains per day. This paper will discuss the innovative approach adopted by CN using Mechanically Stabilised Earth (MSE) to replace the ageing structure, and support the overhead rail.
