All UK tank locos were coal fired. They experimented with oil firing on a few tender locos that were converted, but converted them back to coal after a relatively short time. These particular engines carried 3.5 long tons of coal which as plenty for the outer suburban services they were designed for. They were based on a very successful lineage of similar tanks built and developed by the LMS Railway before the railways were nationalized. Some of the largest British Tank locomotives could carry up to 6 long tons (and more when over loaded) in their bunkers which is almost as much as some tender locomotives. Water was usually more of a problem, although they were usually used on services that stopped regularly and had plenty of opportunity for topping up the water tanks.
