Book Description

Because of the length of the Mount Macdonald Tunnel, approximately 50 minutes is required for each train to traverse the tunnel and for the tunnel to be purged of exhaust before the next train can proceed through it. [...] Shortly thereafter, the train came to a stop on a 8.75-degree right-hand curve, with the head end of the train at the west- end bridge abutment of the Stoney Creek Bridge. [...] The magnitude of the lateral forces at the rail is determined by several factors, including the longitudinal force, the coupler angle, the grade, and the degree of curvature. [...] The footnote indicates (in part): When travelling westward via the MacDonald track, the TrAM Area is 3. When travelling westward via the Connaught track, the TrAM Area is 5. Before departure from Field, the train crew had reviewed the train consist for TrAM restrictions for its routing over the Mountain Subdivision. [...] The NMC will provide instructions to the crew on how to remarshall the train to remove the marshalling violation, and, if the train is able to be moved before the marshalling violation is corrected, what restrictions will apply to movement of the train.
