A number of crossovers (for instance, Westenhanger) are 160km/h (100mph).Colton Jn was I think the first at 70mph - is there anything faster on HS1?
Good shout. Someone's bag almost always goes flying over that one!Worting Junction (90 mph?).
Thanks for both replies - I couldn’t find the information without going to the Sectional Appendix.Good shout. Someone's bag almost always goes flying over that one!
Most seem to be 70, rather than 75mph.75 mph crossovers are fairly common on modernised parts of the WCML, for example.
I think 70 mph crossovers go back to the introduction of HSTs: for example Didcot East Junction on the WR, Woolmer Green, Holme and Stoke on the ER.Colton Jn was I think the first at 70mph - is there anything faster on HS1?
Well before that. I think the 70mph ones at Weaver Junction for the Liverpool lines, both Down and Up, went in with the electrification around 1961. The initial expression for this one was a "two-level junction", just a reference to achieving some superelevation within the pointwork of the diverging route (and possibly some special sleepers). Greenhill Upper went in I think with the closure of the Buchanan Street line around 1968. There seem a lot that were done at 70mph so I would guess it's a standardised design that was developed.I think 70 mph crossovers go back to the introduction of HSTs: for example Didcot East Junction on the WR, Woolmer Green, Holme and Stoke on the ER.
....and Midcalder Junction at Kirknewton - although that's not, strictly-speaking - a crossover.Another fairly fast one in Scotland is the 70mph diverging at Newton West Junction, east of Cambuslang station.
85 unless they change the PS speed.An interesting location to see what speed Avanti's 80x will be allowed over it.
100You'd hope the WCML/HS2 junction at Handsacre would be at least the 110mph (non-tilt) allowed on the Trent Valley line.
I gues the question here is does the OP's definition of crossovers include all kinds of turnout like this?Hasn't the Liverpool route at Weaver Jn gone up to 100mph?
In fact, checking the SA, it's 85/95EPS1/100EPS2, with 95 for Voyagers and 100 for Pendolinos.

There are faster crossovers on HS1 of course, and to come on HS2.

Colton is a Switch diamond + turnout rather than a crossover though isn't it? The Ladders at Colton South and North are both 70mph IIRC (as is Church Fenton east jn nearby)Colton has been 125 each way since it was installed back in mid 80's.
The longest Switch rails then produced.
They're 60mph, right? Is that the fastest on the LUL system?far from the fastest but pretty sure the victoria line has full line speed running over the crossovers at walthamstow central and brixton
Yes.far from the fastest but pretty sure the victoria line has full line speed running over the crossovers at walthamstow central and brixton
Thought Victoria Line was 50mph (motoring to only 47.5mph.)?They're 60mph, right? Is that the fastest on the LUL system?
80km/h (50mph) on the Vic. There's a section or two of 60mph on the outside sections of the Met.They're 60mph, right? Is that the fastest on the LUL system?
Colton South is 70, North is 65mph.The Ladders at Colton South and North are both 70mph IIRC (as is Church Fenton east jn nearby)
The A Stock did upto 70mph but I think some said they had been reduced to 50mph many years before scrapping.The Metropolitan had/has 70mph sections but the S-stock can only do 62mph.
