Quote:1. As TPWS is not giving any warning to the driver - Why we are calling as Train Protection And Warning System?On-board, TPWS is a single system where "WS" comes from AWS and "TP" from TPWS [sic]. The systems differ in that AWS does provide a reminder indication (visual and aural) to the driver for a non-green aspect and/or speed restictions. The TP part is used as a non-fail-safe system to control the train if the train is doing something incorrectly (overspeeding or passing a red aspect).
Quote:6. How the driver identify If controlled signal is passable signal?Can you define what is meant by passable? On CTRL, for example, certain signals may be passed even when red (at reduced speed and under very specific rules). The terminology for those comes from France which is "franchisable" meaning passable.
