Train T


The Train 2T, 4T and 6T were low power piston engines for light aircraft, produced in France. They were inverted, air-cooled in-line engines with the same bore and stroke, differing chiefly in the number of cylinders.

Design and development

In the 1930s Train introduced a series of air-cooled, inverted in-line piston engines for light aircraft. The T series all used the same cylinders, pistons, connecting rods, valve trains and ignition system, combined into 2, 4, and 6 cylinder units of the same layout. The number of crankshaft bearings and throws naturally depended on the number of cylinders, as did the number of cams on the underhead camshaft. Each cylinder had a swept volume of, so the displacements were, and and the rated outputs, and respectively. The Train 6D was a variant of the 6T with increased bore of.

Operational history

Several International 2-litre Class records were set in 1937 by aircraft powered by the Train 4T. On 7 June 1937 M. Duverene averaged over and over in a single engine Kellner-Béchereau E.1. On 27 December 1937 Mme Lafargue reached an altitude of in a Touya, setting both a class and a women's record.
It also powered aircraft on some notable cross-country flights; on 30 December 1937 M. Lenee flew a Kellner-Béchereau E.1 from Elde to Biarritz, a distance of ; the same day M. Blazy flew a two-seat SFAN 5 aircraft from Guyancourt to Champniers, Charente, covering.
Six Train 4Ts were used in the 2 seat, span Potez-CAMS 160 flying boat, a 1:2.6 scale model of the large Potez-CAMS 161 aircraft.
