A fast 309 and 310 service Monday to Saturday timetabled and marketed correctly would do well. There are upto 15 buses per hour at the moment between Battle Hill Drive and Newcastle (58, 306, 309 , 310). If the 309 and 310 was to be made fast Monday to Saturday daytime, the number of all stopping services serving Battle Hill drive would be 10 with the other 6 operating fast every 10 minutes combined. As long as they were timetabled before a 306 wherever possible or on an easier note before a 58, they would gain passengers to Newcastle. Once again, as long as they were timetabled just before another service on the Station Road slip road, they'd do well.
Also, there would be 16 all stop buses per hour between Station Road and Newcastle Monday to Saturday daytime but eastbound with the 58 not serving St Mary's Place with the exception of evening and Sunday journeys to combine with the 309 and 310, there would only be 10 all stop services (well 8 as the 51, 307 run only hourly) from between Haymarket and St Mary's Place to Station Road. Now at the peak times, they would get absolutely hammered with all the short fares particularly eastbound and the 309 and 310 would turn out to be the better choice.
