Data from "The Railways of the Channel Islands", Locomotive Magazine, Volume 20 (15 January 1914 and 14 February 1914) pp. 33-35, 59-61. Works numbers were 916-917 in 1884.
Any similarity to the Isle of Man locomotives produced by Manning Wardle is not at all coincidental, even though this pair entered service on Jersey fourteen years later than the I of M engines. The JR&T opened in 1870 as a standard-gauge railway running 3 1/2 miles along the promenade from St Helier to St Aubin. When the line was extended in 1884 to Corbiere, it adopted the Cape gauge, which was then applied to the other segment.
St Heliers and St Aubins were the first to be delivered to the new track width. These and the Bagnall locomotives shown in Locobase 20288 received new cylinders bored out to 13 3/8" (340 mm) and a larger boiler of 42 1/2" (1,080 mm) diameter and holding 114 2" tubes that offered 635 sq ft (59 sq m) of heating surface area. At that point, they weighed 58,240 lb (26,417 kg).
Data from "The Railways of the Channel Islands", Locomotive Magazine, Volume 20 (14 February 1914) pp. 59-61. Works numbers were 1418 in 1893 and 1466 in 1895.
Any similarity to the Isle of Man locomotives produced by Manning Wardle (Locobase 20040) is not at all coincidental, even though this pair entered service on Jersey fourteen years later than the I of M engines. The JR&T opened in 1870 as a standard-gauge railway running 3 1/2 miles along the promenade from St Helier to St Aubin. When the line was extended in 1884 to Corbiere, it adopted the Cape gauge, which was then applied to the other segment.
Produced by a different builder a decade later than the first two (Locobase 20287), this pair had a slightly larger boiler. The Corbiere and St Brelades, as well as the Manning Wardle locomotives shown in Locobase 20287, received new cylinders bored out to 13 3/8" (340 mm) and a larger boiler of 42 1/2" (1,080 mm) diameter and holding 114 2" tubes that offered 635 sq ft (59 sq m) of heating surface area. At that point, they weighed 58,240 lb (26,417 kg).
