The Inter-City

The Inter-City was a British named express passenger train operated by the Western Region of British Railways (WR) between and via . It connected England's first and second cities, London and Birmingham. 
Introduced in 1950, "The Inter-City" can claim to be the origin of all later usages of the railway term "InterCity" (with or without a hyphen) worldwide.
In the winter 1959-60 timetable, the train became just one of an hourly all-day restaurant-car service between Paddington and Wolverhampton, as the WR service was ramped up to compensate for the absence of trains on the West Coast Main Line during electrification work on the latter.
