Washington County 4-4-0 "American" Type Locomotives

Class 1 (Locobase 2151)

Data from 1899 Brooks catalogue.

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 #2948-2950, produced in April 1898.

The Washington County Railroad Company ran in Maine as an independent line until its takeover by the Maine Central in 1911. According to a list compiled by Mr. Bradley L. Peters in 1976 and preserved on http://www.trainnet.org/Libraries/Lib002/MEC-CO.TXT (visited 5 Aug 2004), it was chartered in 1893 and its major lines opened in 1898. Altogether it operated 115 miles connecting Ellsworth, Machias, and Eastport

The class shown shared the same firebox and had the same number of fire tubes as the 5 Ten-Wheelers that went into production just before in Brooks' Dunkirk Works; see Locobase 2983.

Obviously there was little use for a small 4-4-0 in the MEC as each of these locomotives operated for a little over 20 years, after which they were scrapped.

Road # Year Changed to new # MEC Scrapped

1 21 in 1900 117 Sept 1921

2 22 in Nov 1905 118 Feb 1920

3 23 in Jan 1907 119 Sept 1921

It's possible that #10 (works #3275) was of the same class although it had 63" drivers. That locomotive became #24in 1906 and 120 when the MEC took it over. Its scrap date was considerably earlier -- June 1916.
