Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004. Works #2943-2947, produced in April 1898.
See Locobase 2151 for a short history of this Maine shortline.
In the same month as the three 4-4-0s (1-3) were produced for the WCRR, this quintet of Ten-wheelers also came to life. They apparently shared the same firebox and had the same number of fire tubes as the Americans, which they immediately preceded on Brooks' Dunkirk factory floor.
Unlike the 4-4-0s, however, three of these freight locomotives served Maine for almost 40 years and one fell just short of 50 years.
