Heljan have announced that following the 1366 class models they will be able to use the common chassis and running gear to create models of the earlier 1361 class saddle tank locomotives.
Like the later 1366s these outside cylindered engines were used on several dockside railways, the 1361s being allocated to Devon and Cornwall sheds for shunting on the quaysides handling mineral and china clay exports and around Plymouths dockyards.
1363 was working from Plymouth Laira shed for much of this period, but probably worked from other Devon and Cornwall sheds when required to cover locomotives stopped for repair.
