The engine was unusual in being an opposed piston engine where each horizontal cylinder contains two pistons, one at each end, that move in opposition to each other.[4] Even more unusually, both sets of pistons drove only a single crankshaft; most opposed piston engines have a separate crankshaft at each end of the cylinder. The TS3 engine used a single crankshaft beneath the cylinders, each piston driving it through a connecting rod, a rocker lever and a second connecting rod. The crankshaft had six crankpins and there were six rockers.[5]

The engine was a two-stroke, of compression-ignition with uniflow-ported cylinders.[5] Scavenging was performed by a Roots blower,[note 1] which was mounted on the front of the engine and driven by a long quill shaft from a chain drive at the rear of the engine. In general the engines gained a reputation for good performance, but this quill shaft was somewhat prone to breaking if over-worked.

Those engines had a very distinctive sound and most local authorities seemed to use them for street cleaning, drain flushing and rubbish collection duties.
