Llanigraham

Cheltenham is a very important city and should expect a London service that doesn't waste 10min backing out of Gloucester. There aren't many ways to save 10min that come as cheap as a station on the avoiding line.
Really, an "important city"?
Population 116,447. Not the County town. Not actually a city, just a standard Borough.
Gloucester has a population of 858,300, is the County Town and really is a City.
Methinks you big-it up a little too much.
