Long distance journeys.....
DC Line trains are pretty full; that's why they are in the process of going up to 4tph.
Timetable:
Let's say you do remove all Bakerloo Line services from the Watford DC Line. That leaves you with only the 4 all stations services. Those services take 48 minutes end to end. Your XX:00 stopping service arrives at Watford Junction at XX:48. Add the other 4, that's a departure at XX:00, XX:15, XX:30 and XX:45.
Say we add a non-stop service to the Watford DC Lines. That leaves at XX:12, and would have to arrive at Watford Junction at XX:51. (It leaves just before one stopper, arrives just after the previous one.) That's a time of 39 minutes. That is 6 minutes over the time a non-stop run would take (estimate at 33 minutes given data from RealTimeTrains -
this and
this). If one increases the line speed, that will only increase the time penalty for stopping at stations in comparison to a stopper. Given that trains on the slow lines take 14-15 minutes to do London to Watford non-stop, this makes any run pointless. Either, one doesn't have stoppers on the Watford DC Line (which makes it pointless), or one does have stoppers, which renders any limited stop running on the Watford DC Line pointless.
Population increases, increased mobility of said population, shift to more environmentally friendly modes of transport. HS2 not only addresses long distance travel, but by removing the long distance trains from the conventional network, more commuter services can run. One doesn't have to use HS2 to have benefit from it.
You haven't provided costings for your schemes for me to compare to HS2. Instead, I have used the assumptions from other forum users who have unpicked your "solutions", users who have in-depth knowledge of how the UK railways work.
The Watford DC Lines are for stopping services south of Watford. They are viable.
LO services are now 4tph. The 4th is currently a training service, so is not in passenger service yet.
None of this benefits commuters in and around Birmingham or Manchester, which HS2 does.
The shock: People get a train that takes less time to get them to their destination.
The number of assumptions that have had to made demonstrate that you have not gone into enough detail, nor provided enough evidence.
You have no evidence for this statement.
You have no evidence for these statements. If the alternatives put forward are even close to the quality of yours, God help us.
