I visited the town library of a station I was interested in and found two copies of the 1:2500 maps of the local area. One was dated 1950 and appears to be correct. The other was also dated 1950 but the cartographer had just added all the new roads and houses built in the subsequent 30 years to the original map and not changed anything else. So, for instance, the station and goods yard, which were closed in 1965 and demolished in 1968, were still on the map.
