Heljan Class 37/7 BR Railfreight Coal Sector Grey 37704 Diesel Locomotive

Update 3rd February 2026: Please note that Heljan have advised this model has not met sufficient demand and therefore will not be produced. We apologise for any issues this causes and advise ordering one of the other Class 37 models currently available HERE

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
  
• Oval or rectangular buffers
  

Standard features have also been upgraded and will include…

• XL Plug-and-Play DCC interface
  
• Five separately switchable lighting functions in DCC mode
  
• Separately switchable tail lights
  
• Separately switchable cab lights
