The Class 37 nose housed traction motor blowers and compressor/exhauster equipment according to http://www.railblue.com/Class%20Headers%20v2.0/class_37V.2.htm

There may have been space in the nose for the crew to pass through. Some early diesels were built with doors in the nose to make a corridor connection with passenger stock. These were rarely used and eventually sealed shut.

Yes Jonathan is right.

Traction motor blowers, exhausters, compressors, air reservoirs and other general ancilliary equipment. Class 37s did have connecting corridor doors (hence their distinctive split headcode windows) though I believe they were never used operationally.

Early diesel locos had the "bonnet" design following the LMS prototypes numbers 10000 and 10001. The Chief Mechanical engineer of the LMS at the time (R C Bond) insisted on the design as he wished to afford the crew a measure of protection. Later designs did not follow the principle.
