Welcome to the 

Owners and operators of two CLASS 52 DIESEL HYDRAULIC LOCOMOTIVES on the 
Severn Valley Railway.

Staring down the barrel of a cylinder

Cylinder-heads under reconstruction. Old BR heads are routinely being replaced with a higher quality steel heads which will undoubtedly lead to fewer issues with engine reliability, reduction in demands for running repairs and maintenance, and increased time in traffic - better all round! Simples!

Another shot of the spare "marine" engine undergoing major re-build. She may look a little worn on the outside, but deep inside she's a real beaut....... the engineering on these German engines is quite simply superb.
