Is there really not a crossover at Dr Days Junction to get from the relief line to Feeder Bridge Junction?

Yes, there is!

[froome]

Am I right in thinking that trains heading to Temple Meads from Filton Abbey Wood can now stop at both platforms 1 and 3, which are separated by the footbridge? If so, it will make it awkward deciding which one to wait at.

You want MORE?

I'm now stuck in Huntingdon, so YES please!

Tenerife,  me. Of all the times I  could  have gone on holiday, and now I'm laid  out on a sunbed by the pool, with nothing to console me but sangria and  Mrs FT, N!

I hope there are some sort of electronic signs  to help the poor traveller.

What you CAN'T do is to get from the Down Filton Main (the new bit) to St Philips Marsh Depot.  The Rhubarb curve is bidirectional, and to get to St Philips Marsh a train has to travel on the right-hand track.  (I can't remember which is up and which is down at the moment - not got my drawings in front of me - and anyway, directions have to change when going round one side of a triangle). Anyhow, there's no route to get from the down Filton Main to the right-hand track.  So any ECS^▸ (Empty Coaching Stock) trains for the depot will have to use the Down Filton Relief.  That'll catch an unwary signaller out.

Had a browse at both Trackit and Tracksy but to my scrutiny neither is correct.

Trackit does not show the link from Parkway platform 1 to the down Filton curve but does show this line as if it were the headshunt from Stoke Gifford yard.

Traksy shows the Horfield Junction as if it were just a straight double junction whereas photos posted on this thread show the junction as more of a ladder junction, compare it to Narroways Junction on the same display.

Neither shows the exit from Stoke Gifford yard in the down direction as a double slip.

There maybe other omissions which I haven't spotted so am I being too nit picking ?

For ease of reference S&T^▸ (Signalling and Telegraph)'s excellent diagrams can be found at posts #322 and #455 (these are links)

Does this help

I did consult the two S&T^▸ (Signalling and Telegraph)'s excellent diagrams before posting to ensure accuracy in the above post.

Of course there are, but this is actually a serious matter, not a facetious one. My partner, who is female, commutes back from Filton every day, often having to catch trains late in the evening. It is not the sort of place she wants to hang around alone in the dark, and has little protection from the elements, so if the train to Oldfield Park is late, she will catch the first train to Temple Meads. This was easy when they all arrived at the same platform, but now would involve making a last minute decision, when the train is approaching, to go over the footbridge to the other platform.

There is presumably no reason why just one platform cannot be used for all Temple Meads services. Few, possibly none, are going to be passing others en route.

Wouldn’t using one platform for all trains cause unnecessary congestion in the event of delays, reduce capacity and introduce unnecessary conflicting moves crossing trains over at Filton Junction?

There’s a reason why four tracks were relaid and that’s to maximise flexibility leading to a reduction in delays and allowing two more trains an hour (at least) to operate.

Logic is to have excellent dynamic signage on the bridge "Next train to Bristol Temple Meads will leave at [time] from [platform]" - which is something that's straightforward to do.  One hopes that as the timetable settles in, late changes to line will be negligible.

This reminds me of my youth - communing outbound from the suburban station of Petts Wood in south London which was on 4 tracks ... my regular train - the 07:39 to Orpington / change for the Sevenoaks express was scheduled on platform 4 but on a significant minority of days arrived on platform 2.   Made all the harder to catch because the change was un-announced and the train appeared from a sideline ("round the corner" in Filton terms?) and the change was only apparent a handful of seconds before it pulled in.

In those days, the rail industry took little care of this school traffic, or the contra-flows in the peak and it was very easy to miss;  the departure board at the gate line rarely warning of the change.   I was very fortunate that my Dad caught the 07:43 from platform 1 and would walk across to the 07:39 if it mis-platformed and hold the door open while I dashed across; alas, a unique solution I don't think you have at Filton?

Think I already mentioned that the Bristol Parkway Platform No.1 to Filton loop connection shown on my diagram doesn't get commissioned until xmas 2018/new year 2019.  After that it will be possible for local stopping trains from the Bristol Parkway direction to use Filton Abbey Wood Platform No.2 which is the opposite side of the island platform to Platform No.3 used by local stopping trains from the Pilning direction.  I would assume (!) thats how the timetable would work, so only need to wait on the Island platform for a Bristol TM^‡(resolve) service.  If not then a lot of wasted infrastructure has ben installed.....

[Bmblbzzz]

So which services will use Platform 1?
