HS2 - Government proposals, alternative routes and general discussion

[whole diary]

What real difference would a short DMU^▸ (Diesel Multiple Unit) running a handful of services a day through to Waterloo actually make in the grand scheme of things?  Not much I would suspect.

Indeed - but then an hourly through service all stations Bristol Temple Meads to Salisbury ... and onwards all stations to Basigntoke, Farnbourough, Woking, Clapham Junction and Waterloo ... would make a difference.   

"Where would the trains and crews come from?".   Well - the Bristol to Westbury is already there. In many hours that extends to Salisbury already, and in many of those it doesn't it carries on to Salisbury.   Salisbury to Waterloo is already there.  So it's a bit of joining up that's needed and NOT a handful of (extra) services that need to be found from somewhere.

I do accept that at times that the line into Paddington is not available, but Westbury IS, the though Bristol to London (Waterloo) service would be distinctly busy.   I'm not sure where we're going with 158s, 159s, 165s, 166s and 175s next year - but it's not beyond imagination to suggest that 158s could be replaced on Cardiff - Exeter services by IETs^▸ (Intercity Express Train) not headed to London on those days, with the 158s used to make the Bristol - Salisbury services up to 5 carriages, with 8 onwards to Waterloo.

Thinking of passenger flows + an Old Oak Common blockade, if people did take to a Waterloo - Bristol route in numbers, that's a good point. From the passenger's point of view, unless swamped, it's an opportunity to provide a functional and more accessible alternative though.

The other qualities offered by the route are for another (extant and already well-filled) thread though. If it had not been for the pandemic, they'd still be in the timetable and we'd be grumbling about the Salisbury-Trowbridge blockade suspending them for much of January.

PS Seasons greetings, all.

I think hourly 9/10-car IET^▸ (Intercity Express Train) diversions into Waterloo, in addition to the Euston ones, would make more sense but were ruled out, this Christmas at least, for a few reasons.   As well as the Westbury blockade there's nothing running between Woking and Basingstoke until 5th January so diversions from Exeter via Yeovil/Salisbury weren't possible.

I presume that diverting into Waterloo via Kensington Olympia and Clapham Junction was ruled out early?

Added 75mins and a reversal
