Heljan 3763 Class 37/7 BR Railfreight Petroleum Sector Grey 37705 Diesel Locomotive

Expected Delivery Q4 2026 (Subject to Change at Manufacturer's Discretion).

Forty years after a large part of the BR Class 37 fleet passed through Crewe
Works for mid-life refurbishment, these ever-popular English Electric
machines will soon be available as ‘37/5s’ and ‘37/7s’ in O gauge for the first
time.

Much like the real thing, our Class 37s are also undergoing a major overhaul
to add finer detail, new features and a wide range of changes that allow us to
replicate the many differences across the fleet.

Batch 1 features former split headcode machines in both Class 37/5 and
‘heavyweight’ Class 37/7 guise, with liveries spanning the decades.

To cater for the many small detail variations across the refurbished Class 37
fleet, our all-new tooling will feature a wealth of new parts including…

• Standard or ‘heavyweight’ body
  
• Single piece or split nose grilles
  
• Standard or modified fuel tanks
  
• Cast or fabricated bogies
  
• Ribbed or plain boiler roof panel
