The actual overturning speed of a train is much higher than the limits set by the speed formula, which is largely in place for passenger comfort. There is no hard maximum unbalanced superelevation for European railways, some of which have curves with over 11 inches (280 mm) of unbalanced superelevation to permit high-speed transportation. [15]

All except the Ashmont–Mattapan line operate in tunnels in the downtown area, but no route operates entirely underground, and only 31 out of the system's 153 stations are located underground. The five branches of the Silver Line bus network are also shown as part of the rapid transit system.
Within the DSTT, speed limits are set at 15 miles per hour (24 km/h) in stations and staging areas and 30 miles per hour (48 km/h) between stations. [ 49 ] [ 50 ] During joint operations, Light rail trains and buses were required to wait in the tunnels between stations until the platform was cleared of vehicles ahead; [ 51 ] buses were mandated ...
