What are the systems of semaphore signalling used by IR?
June 21, 2019

In IR's lower quadrant system (Two-aspect Lower Quadrant) the semaphore arm can only be in two positions. The horizontal on position shows the most restrictive indication (requiring the train to stop or slow down or proceed with caution depending on the kind of signal), and a lowered position where the semaphore arm is at about 60 degrees or more

June 21, 2019

IR uses several kinds of signals. Semaphore signals have generally given way to colour-light signals although there are still many places with semaphore signalling in use. Semaphore signals are the older style signals seen widely throughout the country, where each signal has an assembly with an arm mounted on a mast, where the arm can move

Why are multiple aspect signalling systems used? What was wrong with the older systems which had two aspects?
June 21, 2019

Multiple aspect signals, by providing several intermediate speed stages between 'clear' and 'on', allow high-speed trains sufficient time to brake safely if required. This becomes very important as train speeds rise. Without multiple-aspect signals, the stop signals have to be placed very far apart to allow sufficient braking distance, and this

WRs’ Mumbai area EMU numbering and classification
June 21, 2019

WR EMUs are numbered differently, identified by 3-digit numbers identifying the rake and a letter (e.g., 'C') added to distinguish the individual coach in the EMU rake. (Contrast this with CR's use of '72', '70', '76' prefixes.) 'A' : Trailer coach, 'B' : Motor coach, 'C' : Driving trailer coach Hence a 3-coach formation could be something like
