Getting us in the spirit early, eh Chris? Beautiful photo and locomotive.
Video shows a Carette gauge 1 steeple cab (48mm) electric loco cat. # 1088/21 pulling a Carette "D" coach cat. # 135/22/48, all ca. 1911. The locomotive is friction drive with the front axle powered by direct contact between a bushing attached to both sides of the motor shaft, and the wheel rims. Carette gauge 1 is 48 mm, three mm wider than the customary. Some locos and rolling stock bind on 45 mm 1 gauge curves, e..g., the coach in this video, which had to be re-gauged to run on 45mm 1 gauge track.
