Overview

The locomotive had a total of eight uniflow cylinders arranged in two groups of four placed between the 1st and 2nd and 2nd and 3rd driving axles, with rotary steam distribution valves placed over each; a bronze sleeve in the valve body was rotated to control cutoff. Two were connected to the forward pair of the six driving wheels. Four were connected, two each side to the centre pair, with the final two behind the last pair. These drove a jackshaft which operated and reversed the valves, and cut off was controlled by rotary sleeves. The boiler was large and had an unusual integral firebox, lined with

Finance

Paget had initially financed it himself, but unfortunately ran out of money, and the railway made up for the difference. There has been a history on the railways of a distrust of new ideas and Paget and Deeley were not on the best of terms. Lowe suggests that there was great hostility to it.
