And the timetables are often unrealistic. I don't know why it seems to be deemed acceptable for train planners to write bus schedules when it clearly wouldn't be acceptable the other way around.
In my experience the timings come from many sources. The bus company themselves, the company who arranges the bus provision or the TOC, based on their own efforts at timing. In olden days it used to be a man in a Viva Van who was instructed not to go above 30mph! I have known one planner get his preserved bus out to do the timings.
The running times are often not the best. Either too tight or too lax. Some that made me chuckle recently were Leicester to Kettering blockade. Buses got 1 hour to do Leicester to Kettering but if the bus went Leicester to Market Harborough, it was 30 minutes, plus 25 mins to Kettering. Make that make sense? How does a direct faster bus get more time to do the run than the stopper bus which diverts slightly off the route to pick up people?
Or TFW giving 15 minutes from Abercynon to Pontypridd. During the worst peak time it takes that but 90% of the time, it takes 10 minutes or less. Can be done in around 5 minutes if you have a nippy bus at night. Or perhaps them giving buses an extra 5 minutes if they serve Treforrest estate despite the fact most buses go past Treforrest Estate anyway as it's quieter than the A470.
Hope to Cefn-y-bedd via Caergwle. Timed at 10 minutes, between these 3 stops, the driving distance is 1.4 miles. So as not to be sitting around, the bus would have to go 8.4 miles per hour!
The filter of a middle man between the actual bus company and the railway planners is, in my view, a regrettable one because any local company really knows the traffic conditions. When I was planning replacement services, their ability to say, no, you need to allow for the Sunday Market at X or a sports event at Y was invaluable.
There needs to be some more local input into timings but also more adapting to changing traffic conditions. Rail Replacement journey times are often the exact same all day. There is no difference at 1am Monday morning to 5pm Thursday Afternoon and so when buses are constantly late, they just increase the journey time but don't think that at 1am on a Monday, the travel time may be considerably less. The other issue that is common right now is train planners blatantly ignoring comments from on the ground. People on the ground give feedback on the timetable but nothing ever changes. The same situations happen every single time a block is on. The same feedback goes back, that feedback is then ignored and the same issues happen. Some TOCs much worse than others for this but the attitude of 'my way or the highway' is so prevalent within rail replacement bus planning. Yet when it goes to pot, those people are nowhere to be seen and somehow avoid all accountability.
Maybe but if rates were massively increased it's not going to solve the problem immediately if drivers with the appropriate licence aren't available anymore.
If rates were increased and TOCs started requesting buses earlier (Some tocs are now asking for buses far too late and so operators are already fully booked), more companies would be available and willing to take on the work. A company knows their costs and if you get offered £600 to do a duty for the day, the company will sit there and go 'we can make that work out' and take on the duty. If however they were offered £300 for the same duty, when they work out their costs, they say 'we would make a loss and therefore it is better for us to give drivers the day off rather than make a loss on a job'. We can't deny that there is a shortage of drivers but the drivers that are available are simply not willing to take big pay cuts so that the company can take on rail replacement jobs at the dismal rates. There are a lot of companies fighting for more and more coaches to do work which previously wasn't as big and combine that with lower rates for rail, why for for rail when the same bus and driver can be used elsewhere and make mega money. National Express Dupes, Megabus and Flixbus all fighting for operators right now. Staff buses seem to be on the rise now with this mostly going through agencies rather than business-operator so again, firms like Zeelo are fighting for operators. Buses going abroad or buses for foreign tourists coming over to the UK are big business at the moment as international tourism comes back. With the railways being in the state that they are, a lot more sporting events are doing dedicated buses as well. With all of this work available at weekends now, why would people do rail replacement on the pitiful rates?
