Data from "The Locomotives of the Great Eastern Railway," The Locomotive Magazine, Volume 17 (15 April 1911), p. 75; and "Tank Locomotive, Felixstowe Ry.", Locomotive Magazine, Volume XXII [22] (15 December 1916), p. 240. Works numbers were 328-330 in 1877.
The FR&D ran over 13 1/2 miles (21.7 km) of track from Ipswich down to the shoreside town of Felixstowe and had these three small tank locomotives. The LM report says that the Great Eastern was reluctant to take over operations on this recent acquisition, but found itself running trains nonetheless begining on 1 September 1879.
The builder of the three tanks was the immediate predecessor of Avonside Engine. The slender boiler had a tall, thin stack over the smokebox and a milk-bottle shaped steam dome over the first driving axle. Photos show the rectangular tanks over the drivers only and a single piece of sheet metal protecting the crew between weatherboard and bunker.
The trio--Orwell, Tomline, and Felixstowe-- experienced very short careers as they went out of service in January 1886 and were scrapped in May 1888.
