When the VR required further branch line locomotives they again approached Clyde Engineering to purchase more T Class locomotives. The third series would differ again from the first two series, with the short-end hood lowered to improve crew visibility. As a result, the third series were delivered with one control stand positioned for long-end leading operation, with the rationale being that the improved visibility would remove the need for a second control stand as the driver could remain in the same position even when leading with the short-end.
