Meanwhile the Bournemouth - Salisbury express bus service, with no direct rail connection is still working commercially on a 30-minute headway, but evening service has to be council-subsidised. However it doesn't connect to the rail station directly at Salisbury, and the PlusBus ticket coverage doesn't extend to most of the route, to provide a good connection from Bournemouth Hospital along Ringwood, Fordingbridge to Salisbury to connect to the train to Bristol.
The issue with the idea of using buses from school contracts is the peak flow that you would seek to capture between Reading and High Wycombe would be commuters travelling around the time.
Although, with an investment with some bus stops off Burchett's Green slips on the A404, they could run it as an extension of a Maidenhead to Berks College of Agriculture shuttle in peak to spread those overheads.
The Bournemouth - Salisbury X3 isn't just an express bus service, it has local passenger flows and performs the function of being a local bus route along the villages it serves. This contributes to the success of the service - it's not a 'new' route in that sense, it's one developed over 20+ years if not longer with regular intakes of new vehicles every 3/5 years.
I suggested using 'school contract' vehicles for 'new services' based on my experiences of working for large operators. You would want to de-risk the operational costs as much as possible - the Stagecoach opco I worked for costed on a vehicle basis - so working other routes contributed to the vehicle's costs across the working day. So I'd want that peak hour cost covered. This means I'd run at a much lower frequency during those times as the vehicles aren't open to me. Longer term, if the route covered it's costs and generated passenger journeys then I'd introduce all day vehicle workings, but in the initial stages I'd want to cover as much of those operating costs as possible.
Other companies, such as Arriva don't operate the same costing system - they use a route system and each contributes to the overheads of the depot on a traffic light colour system (green for profitable, orange for covering costs but not profitable and red for loss making). Problem is there withdrawing 'red' routes creates more 'orange' ones and the 'green' routes turn orange as the overhead is spread over fewer and fewer vehicles. End result is something like Guildford where they've just closed the garage. Commercial innovation is something not practiced there so ideas about improving services were somewhat alien and people proposing such things didn't stay round long. Far easier to have a network change and remove a bus from the depot...!
I can give you a good example from First Hampshire where they introduced a new express route in August 2004 from Weymouth depot using a Mercedes 709 minibus. It operated as X37 and provided a peak hour link to Yeovil where a satellite site of Bournemouth University was in place, so there was some sort of peak hour flow. The return journey from Yeovil to Weymouth and the reverse afternoon journey was in effect positional, but the service was used by people who were paying concessionary fares (not free at that point).
The route picked off several points of the 212 service (Maiden Newton and Charminster) but stuck to the A37 much of the way offering a faster journey time than the 212 (which found every possible village, phone box, post box and lamppost to stop at on a 1hour 45 min journey but at some time of the week the stops generated passenger journeys). For FirstGroup at the time, such ideas were very innovative.....!
The route ran for almost 2 years - and was subsumed into the Sureline 212/216 service in 2006 which they'd run for a year at that point. They did expand the frequency but it didn't survive long and today there is just one subsidised route between Yeovil and Dorchester. So, even with a humble 29 seat bus working an express route there would be a mountain to climb in finding people to travel on the service.
Thats for a brand new bus including profits on a Monday to Sunday route. Dedicated high spec, at the time brand new buses. Can't be used elsewhere to boost revenue and if the contract wasn't won, the depot would cease.
The 150k figures quoted above were actual running costs for just Monday to Saturday daytime. My figures include profit and Sundays which shows that the numbers must be relatively far off. Yes it may be Reading but even so, it shouldn't so much of a difference.
You can find figures for depreciation on bus company accounts on Companies House. Depreciation, for those not in the known is the accounting method for writing down the cost of a vehicle from new to end of it's accounting life. It can be 10-15-17 years depending on the company and the type of vehicle. A double deck bus would be written down over a longer life than a small vehicle like an Enviro 200/Optare Solo.
Operating Costs include some of that - you also need to include such things as drivers wages, fuel, wear and tear on the vehicle, maintenance and the contribution the vehicle makes to the depot overhead costs (is the depot rented/leased/owned, is the depot newly built, falling down, a hauliers yard with pressure hose?). Is the vehicle an old Dart or a brand new Enviro 400 MMC double decker? The latter will cost more in depreciation than the former, which will cost more to maintain as it becomes older. Not that a 'new bus' is necessarily more reliable!
I have worked in companies where the figure was £150k a year, another operator it was £110k a year. On The Buses, who works at First South West has given a £100k figure per annum elsewhere on this forum which is obviously what they work to there - that's a little lower than I'd expect but all companies are different.
