Brighton Main Line CP6 options study

[SpacePhoenix]

Is the signalling currently 3 aspect? If it is, would changing it to 4 aspect make much difference to the availability of paths?

It may not add paths or any significant extra capacity, but as you will be aware, it would quite possibly result in a small but useful amount of extra "timetable padding" (in laymans' terms).

That said, I appreciate that any reworking of the timetable in that area could well do away with such fantasies very easily...

Whats the difference in acceleration between the DMUs and the EMUs? Surely it only adds seconds to the timings if that?

Equally of course if done right presumably it would add nothing as the DMUs shouldn't be stopping between the junction south of South Croydon and London Bridge anyway (except for the stop at East Croydon)!

Not sure routing via Tkulse Hill would be an option the passengers would like as presumably it would add to journey times!

Perhaps a better saving would be to divert the East Grinstead to Victoria services to London Bridge instead. These currently cross both the slow lines and fast lines from Victoria as well as the slow lines from London Bridge at Windmill Bridge Junction.

The Reigate/Tonbridge or Horsham slows via Redhill could be diverted to Victoria to provide capacity but cross at Stoats Nest Junction (or just north of Purley Station) to avoid conflicts at Windmill Bridge Junction.

Obviously this would change the current routings into London for several passengers meaning changes at East Croydon (although probably removing the need from an equivalent number going to the other terminus). It would also mean in the longer term it would be sensible for East Grinstead to receive Thameslink trains all day rather than rush hours as current proposed (subject to winning bidders changes)

I think the Horsham slows will become Thameslink services. Horsham is a certain Thameslink destination as that is where a sizeable chunk of the stabling will be.

Nobody likes additional journey time, but as I have to sit at Horsham for 10 minutes each evening I have no sympathy.

The additional journey time is exactly why the idea works. 5 minutes extra journey and the turnaround time at London Bridge becomes a healthy 10 minutes.

Plus there will be a small number of commuters who rely on the Thameslink peak time route via Tulse Hill whose journeys will become extremely slow and complicated unless something goes that way, and it makes a lot of sense to me to kill two birds with one stone.

Then the Reigate/Tonbridge Services could go to Victoria - although as 4 coach trains they may become every crowded

Neither Reigate or Tonbridge could take longer trains AFAIK
