Description
Torquil was drawn up shortly after the delivery of Agda and her sisters. He was originally going to be a 0-4-0 tender engine intended for goods traffic but it was decided that he would be experimentaly fitted with an extended frame, trailing wheel and a rear water tank and coal bunker. This made him the first tank engine of the railway. He could under trails pull a heavy train for about 11 kilometres before having to top up on water. He was put into service as a shunting, banking and local goods engine and was considered quite the success. Most of the railways following tank engines would follow the same basic arrangement of a water tank and coal bunker placed behind the footplate.
