GSWRI Class J11
From Wikipedia, the free encyclopedia
In the late 1880s the railways were looking for a new locomotive of sufficient power to work goods trains, of increasing load, in the area around Cork, Cobh and Youghal. Other constraints, in particular the sharp radius of the track on the dock areas, limited the size and coupled wheelbase for the design. From this the Class J11 was developed.
[edit] History
This class of just three six - coupled (0-6-0) side tank locomotives was designed by Locomotive Engineer, H. A. Ivatt, in 1887 for working heavy goods trains between Cork, Cobh and Youghal. Constraints on the locomotive design meant that the coupled wheelbase had to be as short as possible to negotiate the curves in the dock areas but the locomotive had to have sufficient power available for the increasing load of the trains. Under the system emplyed by the Great Southern Railways they became Class J11.
The class survived until the mid / late - 1950s, still working in the Cork area.
