The station usage figures for the year 2008-09 are now out and are available to download from here:

Further to my earlier posts in this thread, here are the passenger numbers for the five stations which opened during the 08-09 year...
1) Alloa - 338,762 (New terminus for Croy Line, hourly off peak service to Glasgow Queen Street)
2) Shepherds Bush - 247,798 (3 tph in each direction on West London Line)
3) Mitcham Eastfields - 199,244 (2 tph to+from Victoria and 2 tph on FCC Wimbledon loop in each direction)
4) East Midlands Parkway - 48,420 (2 tph to+from St Pancras and 1 tph Leicester - Lincoln service in each direction)
5) Aylesbury Vale Parkway - 13,058 (1 tph to+from Marylebone off peak)
So Alloa is the runaway winner, despite having a relatively poor off peak service frequency. Interestingly Mitcham Eastfields seems to have had only a limited impact on Mitcham Junction (interchange with Tramlink and only a mile to the south). Passenger numbers at MIJ fell from 362,217 (in 07-08 ) to 316,466 (in 08-09) - a decrease of only 12.5%.
I imagine both EMT and Chiltern will be very disappointed with the performance of EMD and AVP, which goes to show that you can't build a new station in the middle-of-nowhere and expect people to pay to use it!
