The Class 37 Locomotive Group (C37LG) is a group of rail enthusiasts dedicated to preserving and operating working examples of English Electric Type 3 (British Rail Class 37) locomotives for the general public, and to promote their interest and history, being part of our nation's industrial and railway heritage. The C37LG is a non-profit making organisation.

The C37LG is one of longest established diesel preservation groups in the country, and traces its history back to 1984 when a group of like-minded Class 37 "Bashers" based around Norwich and Ipswich formed a group called the East Anglian Syphon Bashers (EASB).

By the end of 1985, the EASB had metamorphosed into the Class 37 Group, with 'Splitbox' as the Group magazine. Things rapidly progressed over the next couple of years, including a trade stand being set up, 'Splitbox' scooping the national railway press with the BR launch of the 'Triple Grey' Railfreight livery, and, crucially, the launch of the official Preservation Fund at the Midland Railway Centre's 1988 Diesel Gala.

To counter accusations of favouritism towards the early build locos, the Group's monthly magazine changed its name in 1988, 'Splitbox' became 'Syphon!' (no "panel-ist" discrimination here!) which it continues to present day ( produced quarterly). The Group was very active in its early days with sales department visiting events and galas to carry out fundraising to buy their own Class 37. Several classic railtours operated, including 'The Felixstowe Phoenix' breaking the loco-hauled drought on the Felixstowe branch, and the Settle Syphons' setting a believed Class 37 passenger speed record of 109.25mph!

These documents have been scanned and put on this site as a record of the groups history, they are avaiable for members and non-members alike, we hope you find them interesting.
We have also collected together a number of tour booklets for tours which have been hauled by class 37s, which will, in time, be linked with the records in the fleet history on the main site
