Longest stretch of 125mph?

[Crossover]

Berko, given the cant, is a great place to go Pendo watching - they certainly go through at a fair whack! How do the Super Voyagers have a lower limit?mor is the lower limit for 220s only (which will no longer be seen down there of course)

Is it perhaps because 221's tilt more than 390's?

EPS speeds only apply to trains that can tilt, as the 220s can not tilt they are not permitted to do EPS speeds. I have no idea why there is differentials for 221s and 390s, something technical I presume.

Isn't it the other way around (8 degrees for a Pendo and 6 for a Voyager IIRC)?

Would the Trent Valley Railway be in with a good shout between Rugby TV Junction and Colwich, using the middle pair of tracks?

Unfortunately the reverse curves at Atherstone put a spanner in the works at 100mph.
Otherwise it would be 125mph from the north end of Kilsby Tunnel to just short of Colwich - 48 miles.

Probably, as soon as I wrote it I started to doubt myself.

 

[The Planner]

Speeds might go up at Watford Jn after the works complete, but there's still the tunnel at 110mph.

For "might", replace with "won't", Watford doesn't deliver any linespeed increases.

Slough, on the down main, is probably the most concerning one, in the morning peak, should a down service on the relief line and the Windsor shuttle arrive at the same time, all exiting via the gateline on the down main which has been squeezed in between the station building and the platform edge, people running round from one end to the other depending on the press of the queue, maybe 100 or 200, which goes right out to the yellow line (and sometimes beyond), when WHAM! a down main service running at 125 mph passes just a few feet away. I honestly can't see how this one passed any genuinely done risk assessment.

Passed a risk assessment? How regally do people in the crowd get dragged under passing trains? I'm guessing never (unless deliberate) which shows that it's not a risk. Aslong as people stand the correct side of the yellow line it is low risk. The yellow line is present and marked so anyone deciding to stand the wrong side of it is putting themselves at risk by ignoring measures put in place for their own safety.

. . . at Newark Northgate you have the flat crossing so they will be doing circa 100mph (as it has a restriction). Grantham has a curve and it is possible they are also slowing for the tunnel.

The linespeed through, both, Stoke Tunnel 5 miles south of Grantham, and Peasecliffe Tunnel 3 miles to the north, is 115mph. It is the same between the 2 tunnels, including through the station.

Northallerton I wouldn't be surprised if it is passed at 125mph. Certainly some of the stations between Peterborough and London will be done at 125mph.

Northallerton and Thirsk in Yorkshire both have a 125 linespeed. The fast lines though St Neots, Biggleswade and Stevenage are also 125mph.

 

[najaB]

I'll be interesting to see if the speed through stations will be 140mph when the Prius are up and fully running.

....Thirsk in Yorkshire both have a 125 linespeed. The fast lines though St Neots, Biggleswade and Stevenage are also 125mph.

Both platforms at Thirsk face the slow lines and have fences on the fast faces.

So sorry, but why do the 221s have a lower speed limit in places than the 390s? Is it the 2 degrees less tilt or something else? I always wondered why the Chester service from Euston to MK takes one minute longer than the other two. I assumed it was slower acceleration.

I think your totally correct in saying the reason is due to 2 degrees less tilt on the 221s

There's a rule somewhere that states that platform tracks can only be used above 125mph if there are no passengers on the platform at the time. So if speeds are increased through stations where the platforms are on the main lines, either new platform loops must be provided or staff must clear the passengers off the platform when a high speed train approaches and only let them on the platform after it has gone.

 

[Stampy]

Think the speed limit through Peterborough is 105.

 

[Marton]

Appendix A shows 105 southbound on UF and a change from 105 to 115 half way through station northbound on DF which doesn't have a platform face.

Is being splatted at 140 that much worse than being splatted at 125?

 

[Mike395]

I'd assume it's more to do with the risk of the increased windspeed on the platform just after a train passes (for which the technical term evades my memory at this moment )

 

[The Planner]

If 140mph increases the chances of getting sucked off the platform I am all for it (you were all thinking it, don't deny it.....)

That could only happen on the Gospel Oak to Barking Line

It's probably a line in the sand thing a bit like not allowing level crossings. Seen to be a big risk so don't do anything to make it worse.

Thought so, I can remember the 115 sign on the DF (between the NEW P3 & P4)

At least they now give you a warning on P3 now when a fast train is due to pass.... :roll:

Turbulence?

I was waiting for 40 minutes at Barrow Upon Soar this afternoon. There were numerous fast East Midlands Trains passing by the station.

What is the line speed on the MML like? It is certainly slower than the ECML and WCML.

I can tell you there are some stretches of 125 mph running south of Leicester, and that its closer to 100/110 in the environs of Loughborough station.

Can't be any more specific, though, I'm afraid!

110mph through Barrow upon Soar. There is some 125mph on the midland mainline, all south of Wellingborough - apart from a small section between Loughborough and half way to East Midlands Parkway. There is sections of 120 north of Wellingborough, between Leicester and East Midlands Parkway especially.

Platforms 1 and 2 at Didcot PW are 125 mph, so they're right on the limit. There's at least 2 tph each way that do it normally, the Swanseas and alternate Bristol TMs.
