Allman's had their own locomotive, the first one known as Allman's Coffee Pot from its archaic appearance and its replacement, a Peckett, ended up in GSR hands after the closure of the distillery.
That's not to say a loco could have been borrowed or leased from the CB&SC if their own was out of traffic, six coupled may have been a bit big for a poky distillery, the Peckett was like a toy, size-wise.
