Ok..will an HST be back on diagram today..or will we have an IET substituting for an HST tomorrow too?

It looks like an emergency stop took place or maybe they are advertising maximum braking capability :lol:

London Underground braking on open air sections under ATO seems to be around 5%G. A Javelin driver friend tells me they are advised to stay well within maximum braking capacity. He claims to use no more than 50% braking capacity as a rule while he acknowledges other drivers may use more braking...

Any bets as to how long before the first Azuma in passenger service ends up in diesel mode only ..under the wires ;)

What services are the 331s likely to be used for?

Have todays Plymouth and Penzance diagrams recovered to the booked HSTs after yesterdays substitution?

The 800's will potentially offer faster journeys - at least a saving of apps 1 minute on sections where the trains can run in electric mode at 125mph. On sections with lower speed limits, the difference may only be an advantage of 30 seconds or so per station to station stop. But all that...

Last 5 days..it did not arrive on time. That is zero 0%

It will be interesting to see how punctual the Norwich in 90 service will be. I was checking Realtime Trains reported timings for the fabled Edinburgh to London in 4 hr service recently, and they reveal it rarely achieves its 4hr timing - usually at least 5 to 10 mins late each day.

Using a claimed 'acceleration rate is misleading, as no train maintains a fixed acceleration rate across the speed range. Probably the class 91's seem to have the most linear speed vs time graph up to 100mph compared to other stock. And two trains that appear to accelerate in the same time to a...

Wow the 331s look like they will be very fast indeed 0 to 100mph in between 80 and 90 seconds!!

The figures in Rail Express are usually the best available in dry conditions and based on several runs. Obviously we try to use figures taken on level track. And as such they provide a realistic comparison between the various trains. The same way 0 to 60mph figures for cars can vary from one car...

So no shortened formation then? A full 9 coach plus DVT?

Can someone enlighten me as to the PR *BS* that refers to these as having 'bullet train technology'???

How are preparations for Norwich in 90 gearing up? Have they managed to marshall together a loco and rake of coaches for it yet?

Yes..an ex GC buffer fitted set with a shorter rake of 6 coaches including a first coach reclassified as standard class!

The CBTC section commences at the East end of the Stratford electric line platforms. Operationally there has to be a reason connected with that.

How confident can we be that the remaining diagrams will all be fulfilled by a HST as booked?

I'm not convinced the Azuma's are any more comfortable! Having recently spent a few days sampling LNER Mk3 and MK4 coaches, i can say with some certainty that both environments are much nicer places to sit for several hours - comparing with GWR 800 and 802 stock. But to put things into...
