GER G16 Class 4-4-0 230
In 1884 Worsdell built an experimental 2-cylinder compound 4-4-0 locomotive for the GER, No. 230. It was identical to the G14 class 2-4-0, except that it was fitted with a leading bogie to provide room for the larger low-pressure cylinder and - like most compound engines - the boiler pressure was higher than normal, at 160 lbs. psi.
In 1892 the G16s were regarded as surplus to requirements and No. 230 was rebuilt with G14-type simple-expansion cylinders. Two years later, all eleven engines of the class were given new boilers, and they continued to give useful service until withdrawn in 1902-1904.
