In 1912 Train was building metal monoplanes similar to Nieuports and Borels. They had all-covered fuselages and simple rectangular rudder and elevators; the 2-wheeI undercarriage had 6 legs like the Hanriot.

   (Single-seater: span: 8.5 m; length: 8 m; wing area: 16 sqm; weight: 240 kg; speed: 78 kmh; 20 hp Darracq, 40 hp Anzani, or 50 hp Gnome)
   (2-seater: span: 9.9 m; length: 8 m; wing area: 20 sqm; weight: 270 kg; 40 hp Anzani or 50 hp Gnome)

   A drawing appeared of a different monoplane, with gracefully curved underbelly, split vertical surfaces above and below the rear fuselage, trapezoidal wings with wing-tip ailerons, an undercarriage similar to the Bleriot XI but with 2 long curved skids beginning under the fuselage.
   By the end of 1912 the heavier-than-air designs of Astra were merged with those of Nieuport, and an entirely new Train design appeared, a 3-4-seater monoplane with an all-covered fuselage, apparently inspired by the Nieuport. E Train, Constructeur was painted on the fuselage. The engine was fully cowled; the undercarriage resembled that of the Hanriot, a rectangular box-frame with trailing skids fore and aft. The upper pylon was an odd 3-Iegged tower from which the guy-wires braced the long wings - probably the same wings used on the Astra-Train. The triangular fin was later removed in favor of a balanced rudder; the large rectangular elevator had a box cut-out for the rudder.

   (Span: c 13 m; length: c 8 m; wing area: 24 sqm; 70 hp Gnome)

   In 1913 Train was reported flying Nieuports at Mourmelon.
