As a continuation to the first post, I would like to add the following facts about the Deccan Queen:-
1) Was started on 01st June 1930 by Great India Peninsular Railway (GIPR) which is today called Central Railway. The train runs between Bombay and Poona. The train started its initial services from Kalyan to Poona.
2) The Deccan Queen has several firsts or 'among the firsts' to her credit: she was India's first superfast train, she was the first long distance electric hauled passenger train, she was one of India's first vestibuled trains. The Deccan Queen was the first to have a Ladies Only car, and amongst the first to feature a diner (dining car).
3) It is interesting to note however that the Deccan Queen was originally intended exclusively for the Colonial overlords. Due to this, she was initially run as a weekend special for the 'goraa sahibs' (white gentlemen). For over a decade, it was considered unprofitable to run the train during the week, due the poor patronage on weekdays. It was only by 1943 after Indians were allowed on board did the clientele pick up, and traffic built up enough to justify a daily service. The daily service started on 26.04.1943. Gradually, the Deccan Queen came to be known as a 'husbands' special', catering to men who spent all week working in Bombay, and returned to their families on weekends. Nonetheless, an increasing number of working women too had become part of the passenger profile of the Deccan Queen.
4) In the earlier days, the train took 2 hours 45 minutes, and today it takes 3 hours 15 minutes
5) Initially, the train was introduced with two rakes of seven coaches each, painted in silver with scarlet mouldings, and the other with royal blue with gold lines. The under frames of the coaches of the original rakes were built in England while the coach bodies were built in the Matunga Workshop of the GIPR.
The original rake coaches were replaced in 1966 by anti-telescopic steel-bodied integral coaches built by Integral Coach Factory, Perambur. The new coaches incorporated improved bogie design for better riding comfort as well as improvements in the interior furnishings and fittings. The number of coaches in the rake was also increased to 12 from the original seven.
In 1995, the rake was changed, further increasing the seating capacity and improving the pantry facilities. Over the years, the number of coaches in the train has been increased to the present level of 17 coaches – 4 AC chair cars, one buffet Car, ten second class chair cars and two second class cum brake vans.
In March 2020, the Central Railway decided to give the train a makeover by upgrading its coaches to German-made LHB coaches, which have better safety features, better suspension system and better riding comfort.
6) When it was introduced in 1930, the Deccan Queen was hauled by WCP 1/2 DC passenger locomotives. From 1954 till the 1990s, it was hauled by a WCM-1/2/4/5 DC mixed locomotive. From the late 1990s till present, it has been hauled end to end by a WCAM-3 or WCAM-2/2P DC/AC locomotive of the Kalyan (KYN) shed. Starting 1 June 2018, on its 88th anniversary, it will be occasionally hauled by the WAP-7.
7) Why does the Deccan Queen not halt at Kalyan, when all major trains halt here.

The WCM series engine, my favourite engine. I call it the Ambassador of locomotives. When these engines were stopped by Indian Railways in the late 1990's for better engines, these engines still ran with the Deccan Queen for nostagia. By year 2000, all units were withdrawn due to frequent failures and were phased out.
