SHOLAY's famous train chase sequence and a similar one in NORTH WEST FRONTIER (1959) (Did You Know - 11)

Hi Amit Sinha,
Thanks for visiting and writing in but I would like to clear the confusion here about its India On Location Shooting.
The film was majorly shot in Spain but a few parts were shot in India which is mentioned at many places but I have one very Logical and Basic reason of my own before sharing that :

1. If you have watched the film then you must remember the Indian subject on which it has been made and the number of Indian artists featuring in it including I. S. Johar. Now I dont think it was more logical to take all those artists abroad and then shoot ther sequences there instead of shooting them in India only.

2. Secondly here are some instance where it is mentioned that it was partially shot in India.

where it is said :

The following information is from a supplement called "Railway Films of the Raj" by Ray Ellis, published with the Indian Railway Study Group Newletter No.9, in January 1993.

A large part of this film was shot on location in Spain, on the 5'6" gauge Zafra-Huelva Railway, of the RENFE. Originally built by a British Company, the line runs parallel with the Spanish-Portuguese border, and has some spectacular bridges and some very Indian looking scenery. The little tank engine used "Empress of India" is one of four 0-6-0T's built by Kerr Stuart (works nos 713,714,715 & 725) in 1900 for the South of Spain Railway, and later RENFE 030.0209-212. The engine used being modified to look more like a locomotive filmed in India, which included the fitting of 'chopper' couplings.
For filming sequences on the sound stage at Pinewood Studios, full size replicas of the locomotive, rolling stock and part of the bridge were constructed, with Pinewoods usual remarkable accuracy.
Some scenes were also filmed in India using metre gauge trains, somewhere near Jaipur. These include the departure of the 'refugee' train and the scenes where the 'escape' train catches up and passes the 'refugee' train. The 'refugee' train is hauled by an OJ class 4-4-0 (built by Bagnall in 1943) and the 'escape' train is hauled by a TJ class 0-6-0T (built by Bagnell in 1942, and sent to India, despite having been ordered by a steelworks in Turkey!). This later engine was also heavily modified to look more like the modified locomotive used in Spain.

This is an official review by Alan Bacchus where he mentions that it was also shot in India.

I hope the confusion gets clear with this but no doubt Ramesh Sippy got inspired from these scenes for his SHOLAY famous train sequence.

Cheers!
