India is one of the countries with the largest network of railways spread over every nook & corner of the country. Needless to say, it requires a large resource of man power for every sector of its operations. Recently a major shift was seen where by the railways have a taken a decision to shift from their self-generating cars to End-on-generation cars, to reduce both cost & time. A major time saving is claimed with respect to maintenance & also the number of times maintenance would be required for each car & equipment. Railways generally faces a lot of problem regarding time consumed for maintenance & which is an unavoidable part of the process. This paper is an attempt to show a comparative analysis regarding the time saved in maintenance between two similar equipment of these cars. This analysis also brings about the fact about how railways now requires only a fourth of the time to complete their maintenance process & help gear things faster & smoother, by increasing quality & efficiency.
