Gwalior Light Railways 2-8-2 Locomotives in India
Class Details by Steve Llanso of Sweat House Media
Class 26 (Locobase 20687)
Data from [
], last accessed 16 December 2021. Works numbers were 4400-4403 in 1928.
This Mikado quartet accommodated the very skinny gauge railway by putting the frames outside of the drivers and reducing all of the proportions except for the cab. Their boilers used Belpaire fireboxes to produce the steam.
