That's a lot of work for little benefit. If station 'a' has always been at 'n' mileage, then think of all the paperwork that needs changing. Cutting routes into pieces over different years, such as the North Devon line, would've meant changing the mileages more than twice. It's not just the...

Risborough to Bicester South is not so bad since the last resignalling. Bi-di is however quite restrictive. It's not so difficult to maintain 100mph with a good separation with the existing timetable and allows for some gaps to fit other moves well enough. I agree with @The Planner for...

High Wycombe no longer has space for 4 tracks since the platforms were extended and realigned. You'd need significant remodelling to make room to do so and keep the through line speed, which is itself already restrictive. The former subway (extant but disused) was also unable to accomodate...

Whilst it has 2 tracks, the covered way at Gerrards Cross is 4-track width. You would however need to rebuild the viaducts at Harefield and between Denham Golf Club and Gerrards Cross. I'd still take loops at Beaconsfield if you're offering, but the lines were realigned for higher speeds...

Probably no worse than any of the other tunnels between Marylebone and there. The tunnel between Snow Hill and Moor Street has however always appeared to me from the driving cab as being quite cavernous. Not sure if I have the dimensions immediately to hand however.

It's difficult to get quantifiable data. How many instances of this go unreported and how many get posted online and not form part of the statistics? It probably happens more frequently than figures can count on. If I recall correctly, this topic has featured on the forum before. At a...

Not much, if any. A lot was replaced with Island Line bespoke signage and has since been replaced again. However the former NSE running in board at Shanklin was sprayed over with an arty 'Welcome to Shanklin' instead. A lot of former signage from NSE and earlier and later is all housed at the...

Way off topic for this, but putting it very simply it's either hardwired by programming code (ACI) or the more revolutionary (WACI) which works it all out by logic (mostly!).

Are you asking a question?

In addition to what CyrusWuff has correctly said, the timetable plan since COVID has meant it's not needed to be routinely used. I can see potential benefits in further deployment in the future depending on what future plans look like.

It is possible, yes. But not routinely used for a few years now.

Apart from those that split out from co-located offices that is.

There is no allowance for a good delay or bad delay. A delay is a delay and has to be allocated to root cause. Bigger or smaller delays are neither here nor there and can't be compared to ticket purchases. The DAPR (Delay attribution principles and rules) is publicly available online via the...

There have been temporary formations for different lengths of time over the years and as a consequence, the mileages accrued so vary from vehicle to vehicle. It's never been a problem in respect of reforming the units and then their respective maintenance regimes. It's just that it has to be...

Communication/Transmission based train control. From Finchley Road, they are Swiss Cottage, Marlborough Road and Lords.

BBC this, but no details on the railway locations (at least on line that is). The street scenes associated were filmed around Rochdale, but I don't sign the route and I have no idea whether the scenes pictured fit the bill for this area or not.

Anyone fancy having a stab at this location? Looks to be a former marshalling yard/depot location left of the tracks and a 2-car Class 108 unit passes shortly before the camera pans to the left.

What a peculiar distinction. Given that Bordesley stops have been made on Chiltern services for a long time, why a trial dated for one year ago should made a difference appears particularly bureaucratic. But hey, it's the railway!

Whilst I can't confirm the actual date, I can confirm with authority that it has been for some years now (in excess of 20).
