This gallery is an archive for
all my photographs of English
Electric Class 50 locomotives
(see www.Class50.net), both
during their days in active
service with British Rail (BR)
and now in their subsequent
restoration and preservation.
There is also a collection of
pictures taken in the mid-1980s
that provides a flavour of the
numerous types of locomotive
that were in use throughout
the national BR network during
this period.
THERE WILL BE NO MORE
UPDATES TO THIS GALLERY.
ALL EXISTING AND FUTURE
PHOTOGRAPHS WILL NOW
APPEAR AT:
