I purchased this as an accessory to my books on the history of railways in the London area. This, along with Joe Brown's superb books, proves invaluable for tracing those the numerous lines that criss-cross the city. Very useful.
I have an original linen backed edition of this map, (somewhere), so I knew fairly well what it would look like. This shews what lines were available on the day that Oscar Wilde was released from Reading. (He took a Great Western train from Twyford to Westbourne Park). It includes also some tram routes. I intend to use this map in conjunction with other maps of London through the ages and railway books published by Old House Books and available though Amazon. It's a good purchase. Have fun!
