Class Details by Steve Llanso of Sweat House Media
Class 3 804 / 5 804 / 7 014 (Locobase 13434)

These adhesion-forward locomotives first entered service as passenger engines in 1857 (Locobase 13371). After the conversion, the stubby-looking terminal switchers had improbably tall, delicately spoked drivers with long side tanks.
Withdrawals began in 1908 and continued through World War One.
