Close-Up: Graham Farish N Gauge Class 37/7 'Heavyweight'
In their Autumn British Railways announcements, Bachmann Europe revealed a brand new N Gauge Class 37/7 'heavyweight' tooling for the Graham Farish range, representing a sub class of the iconic English Electric 'Tractor' never before produced in the scale.
44 Class 37s were reworked into this subclass which was similar to the 37/5 except for the plating over of a bodyside window and the addition of a ballast weight to give extra haulage ability on the heavy freight trains such as coal and metals in South Wales, work they proved very suited to.
The new models have been designed from the rails up and bring factory fitted DCC sound to the Class 37 in N Gauge for the first time and N Gauge News was able to take a close-up look at the livery samples for each of the four models planned during the 2026 International N Gauge Show.
