I know this is slightly off topic, but is there is a good source, or publication, which details which type of SR EMU's worked each traffic diagram on each line/route in the period during 1970s/80s/90s? For example, I believe '4 Cor' stock used to work the 'Coastway' services emanating from Brighton in the early 1970's before they were displaced by SR Design '2 Hap' stock which in turn were replaced by BR Standard '2 Hap' stock in 1976 (ref: 'Slam Doors on the Southern', Michael Welch). I know '4-Cep' stock worked in the area during this time as well but I presume they were on services from London Victoria rather than local services.
I am particularly interested in the Eastbourne to Hastings line during this period.
Is one of David Brown's book my best bet?
