How were the 9 older zones created out of the former independent railway networks?
July 16, 2019

Around 1950, legislation was passed allowing the central government to take over many of the independent railway systems that were in operation. In 1951, the following zones were created: SR — April 14: From Madras & Southern Mahratta Rly., South Indian Rly., and Mysore State Rly. (about 9660 km). CR — Nov. 5: From the GIPR, the Nizam's

Why do locos sometimes use the rear pantograph and sometimes the front pantograph?
July 16, 2019

There is in principle no difference between using the front and the rear pantographs for most locos as each is fully capable of delivering the required electric current from the catenary to the loco. (The AC-DC locos are special in that each loco is intended for a different traction supply.) Generally on IR there is no need for both pantographs to

When does the driver have to lower and raise a pantograph on the run?
July 16, 2019

Normally, pantographs do not have to be lowered and raised on the run. The principal exception is the case of the AC-DC switchover by the WCAM series locos as described above. Other than that, there are a few points where the catenary has a gap (no cable physically present, not even a neutral or dead section), for instance at level crossings where

What happens if the pantograph isn’t lowered when the loco enters the dead zone?
July 16, 2019

Usually there is no problem, if the master circuit breaker of the loco has been switched off. In most cases of neutral sections, therefore, the driver does not have to lower the pantograph. If a live loco enters this section without its master circuit breaker turned off, then there is a possibility of sparking or transient disturbances, which can

How do the AC-DC locos (WCAM series) switch from one power source to another on the run?
July 16, 2019

At DC/AC changeover points as on the Virar-Vaitarna section, WCAM locos can switch from one power source to another without stopping. The WCAM-1 has a selector on the rightmost side of horizontal control panel for selecting the pantograph. It has four positions, DC, AC, DC-ALT and AC-ALT. In DC and AC-ALT mode, pantograph with two collector shoes

How are DC locos swapped for AC locos at the point where traction power changes from DC to AC?
July 16, 2019

Today while the the Mumbai area is still mostly at 1.5kV DC, there are a couple of important AC-DC transition points such as Igatpuri -- now Kasara -- and Virar. In time, when 25kV AC becomes the norm and DC traction is decommissioned, these transitions will be history and there will be no more traction changeovers! Sad for railfans, but perhaps
