This book is a consolidated version of my earlier two books titled "DC Locomotives of Indian Railways" and "AC Locomotives of Indian Railways".The Electric Locomotives are set to become the supreme workhorse of the Indian railways in a few years and are regarded as to the most advanced and efficient of all locomotives. So, it may be a surprise to all that they are one of the oldest locomotives of India, with the first being introduced in the 1920s. In this book, we look into the details and history of these locomotives.
