EASY ON, EASY OFF

摘要

On many passenger rail systems, the Bridge and Building (B&B) Department is an important part of an effective track production program, keeping heavy track production units moving forward. Work on high-level and low-level passenger platforms falls under the responsibility of B&B. On high density passenger rail systems with three or more main line tracks, such as Amtrak and Metro-North, great consideration must be given to supporting loading and unloading of passengers in stations during track production. This task usually involves some sort of station platform modification and is traditionally given to B&B. Safe and efficient boarding of passengers while production equipment is in a station's track block is important for customer loyalty.
