Built in 1933 by Sir W.G. Armstrong Whitworth Company, UK. This 15-seater railbus was on service on the Kalka-Simla line of the NR. The bus is dual braked (mechanical and air brakes), which is commendable for a railway vehicle of its time. Like all other railcars on the Kalka-Simla line, this one too is fitted with a swivelling headlight, which turns along with the curvature of the track on the steep hill line.
