Here are some passengers per train figures for the average number of ticketed people leaving or joining each train.

Heysham. 28 trains per week, 6788 passengers per year, 4.6 passengers leaving or joining
Roman Bridge. 60 trains per week, 321 passengers per year, 0.1 passengers

Roche is to have its service cut by 50% under the new Greater Western franchise. Melksham is to have its service cut by 70%. I know of no threats to the other services listed; I note that Hough Green (in the consituency of the transport minister Derek Twigg) has less that have the boarding and leaving traffic per train that Melksham has, and ask him to consider what local reaction he would get if he proposed reducing the service ...

In 2002/3, Melksham was at number 1974 out of 2406 stations on the main rail nework for ticket sales too / from.  Please email me is you would like me to work out a similar comparison to the above for ANY other station.
