Can a train instantly stop?

Trains can't stop quickly or swerve. The average freight train is about 1 to 1¼ miles in length (90 to 120 rail cars). When it's moving at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake.

Here in the UK passenger stock is normally limited to a maximum deceleration of 9% of 1G for normal braking (about -0.88m/s/s). In emergency braking that can go up to 12%G (about -1.18m/s/s). Some trams have track brakes that can stop a LOT quicker than that.
