Heljan O Gauge 3742 BR Class 37/4 INTERCITY/Mainline Livery
Class 37/4 locomotives were refurbished class 37s equipped with electric train supply / heating generators for service on the North of Scotland and welsh Borders routes. The arrival of Sprinter DMU trains for regular services in the late 1980s saw the 37/4s shifted to other duties. Several were painted in InterCity livery for hauling the luxury train tours of the Scottish highland lines, taking regular class 37 freight duties when not required for tour service.
Following the second batch of Heljan O gauge class 37 with centre headcode the later 37/4 version is now under development.
Heljan locomotives feature a heavy diecast chassis block and twin motors, one driving each bogie. Weighing in at over 3 kilos the combination of weight and powerful motors results in a smooth running locomotive with significant inertia for realistic starts and acceleration. Attention to detail in the design of the bodyshell to incorporate accurate profile, grilles and louvres results in a very pleasing model of the 37, which proved to be one of British Rails' most successful and widely travelled diesels.
