Data from DeGolyer, Vol 72, pp. 343+. Works numbers were 57740-57741 in April 1924.

Piston valves measured 10" (254 mm) in diameter and the firebox had 17 sq ft (1.6 sq m) of arch tubes.. This pair of Mikados used exactly the same boiler and grate as the Pacifics shown in Locobase 15293.

Class Standard Light Goods/XD (Locobase 20281)

Data from "Six 'XD' Class 2-8-2 Locomotives for Madras and Southern Mahratta", Vulcan Magazine, (1948), archived at [], last accessed 24 August 2017. See also [], last accessed 24 August 2017. Works numbers were 5744-5749 in 1948.

Part of a series of designs created in the mid-1920s to meet Indian railway requirements. Similar in basic layout to the larger XE (Locobase 4274), the XD's axle loading requirement set a cap on weights and thus the size of the major components. According to IRFCA, XD stood for "X Dominion" and more than 200 were produced.

Vulcan's 1948 article noted that this particular order originally was negotiated in March 1940, but hung fire for several years. By that time, Vulcan had delivered several batches of XDs, including 4 for the Nizam's State Railway in 1931 (works 4554-4557), 3 to the Southern Indian Railway in 1934 (works 4615-4617) , and 4 to the M&MS in 1938 (works 4775-4778).

When it was delivered in 1948, the class had the 24 sq ft (2.23 sq m) of the earlier engines, but poppet valve gear now delivered steam to the cylinders through piston valves.
