Data from "Steam Rail Motor Coaches", The Locomotive Magazine, Volume XII [12] (15 November 1906), p. 184. See also "The Locomotives of the Isle of Wight Central Railway", Locomotive Magazine, Volume XXVII [27] (15 September 1921), pp. 317-319. Works number was 2663
This little steam motor resembled many of the other such vehicles that came into service. Although the engine bogie could be separated for maintenance, the combination could only operate together. The carriage rolled on a rear bogie and sat six first-class passengers in a compartment measuring 6 1/2 ft (1.98 m) long, and 44 2nd-class passengers in its 26 ft 1 in (7.95 m) compartment. The luggage compartment capacity was rated at 1 long ton (20 cwt or 2,240 lb).
According to the LM report, the steam motor worked the Ventnor line and would "...perform the full service during the winter months and supplement the service of ordinary trains on other sections during the summer."
It remained in service until February 1918, when the engine section was sold for docks duty at Middlesborough.
