# MGWR Class 1

Midland Great Western Railway (MGWR) Classes 1, 2, 3, 4, 5 and 13 were 2-2-2 locomotives acquired over the period 1847-1862 serving the railway in its formative years.

## MGWR Class 1

The MGWR Class 1 were supplied by Thomas Grendon and Company from April 1847 with Dunsandle performing the trials and opening run. These engines were a replacement for a cancelled order from J & R Mallet of Seville Ironworks Dublin and arrived before the earlier order for MGWR Class 2 from Fairbairn. Juno was later converted into a 2-2-2T tank locomotive.

With the exception of Class 13, all subsequent locomotive builds for the MGWR were of engines with the driving wheels connected by coupling rods for better adhesion. The MGWR Class 5 engines were themselves rebuilt as 2-4-0s beforce withdrawal and renumbered in the range 88-93.

## MGWR Class 13

The final set of six 2-2-2 passenger locomotives for the MGWR designated Class 13 built by R and W Hawthorn of Leith, Scotland. They had double-sandwich frames, outside springs and 15 in × 22 in (381 mm × 559 mm) cylinders. Their driving wheels were the largest of any MGWR 2-2-2 locomotive, being 6 feet 6 inches (1.98 m) in diameter. They were renumbered 43-48 between 1871 and 1873, switching the number range with MGWR Class 12 so all passenger engines could be numbered 1 to 48.} Their final years saw them displaced from main line to branch services.
