Which crossover has the highest speed limit?

[PGAT]

Do you know which crossover has the highest speed limit?

 

[hexagon789]

There are probably higher rated ones somewhere, but the fastest ones I know the location and speeds of in Scotland are

65mph crossovers between the various tracks on the 3/4 track section between Shields Rd and Paisley (linespeed is 75mph here).

70mph diverging from the E&G at Greenhill Upper (linespeed is 100mph).

 

[30907]

Colton Jn was I think the first at 70mph - is there anything faster on HS1?

EDIT: wrong again - 125 apparently (though not a crossover).

A number of crossovers (for instance, Westenhanger) are 160km/h (100mph).

 

[Railsigns]

75 mph crossovers are fairly common on modernised parts of the WCML, for example.

 

[D6130]

Worting Junction (90 mph?).

Good shout. Someone's bag almost always goes flying over that one!

Thanks for both replies - I couldn’t find the information without going to the Sectional Appendix.

Most seem to be 70, rather than 75mph.

There is a 100mph crossover at Rugby from the Down Fast to the Down Coventry.

 

[DeparturesBeck]

Rugby Trent Valley Jcn - Down Fast to Down Coventry is 100 PS 115/125 EPS

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.

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.

 

[D6130]

IIRC, the 90 mph crossovers at Worting Jn - since replaced by new ones with altered geometry - were installed in 1966 as part of the Basingstoke resignalling for the Bournemouth electrification. The 70 mph crossovers at Hanslope on the WCML were installed in around 1971, replacing the original lower speed junction for Northampton at Roade, a few miles to the North.

75 mph GWR down fast west of Hayes diverging to Heathrow. 125 mph towards Reading.
When first installed used to be 85mph.

 

[LNW-GW Joint]

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.
An interesting location to see what speed Avanti's 80x will be allowed over it.

There are faster crossovers on HS1 of course, and to come on HS2.
You'd hope the WCML/HS2 junction at Handsacre would be at least the 110mph (non-tilt) allowed on the Trent Valley line.

 

[Peter0124]

Another fairly fast one in Scotland is the 70mph diverging at Newton West Junction, east of Cambuslang station.

....and Midcalder Junction at Kirknewton - although that's not, strictly-speaking - a crossover.

 

[Hadrian]

I observed (from passing trains) some of the crossovers at Hanslope being installed on Sunday 18th October 1970. On that weekend, and other weekends around that time, two of the four tracks of the WCML remained open throughout the normal operating day and the timetabled train service operated unaltered. I have often wondered whether works like that would now be done with adjoining tracks in use. As I remember it, there were temporary speed restrictions on the open tracks. The four crossovers between the middle two tracks were installed with trains passing on either side (on the Down Fast and Up Slow). I assume that the new junction was brought into use several months later.

85 unless they change the PS speed.

100

I gues the question here is does the OP's definition of crossovers include all kinds of turnout like this?

 

[Ploughman]

Colton has been 125 each way since it was installed back in mid 80's.
The longest Switch rails then produced.

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)

 

[furnessvale]

Can any active perway operatives help out us old retirees by adding what euipment is used at these speeds, eg F24 or G28 or even split G28? (Probably old method of describing P&C in this modern world)

 

[AzureOtsu]

far from the fastest but pretty sure the victoria line has full line speed running over the crossovers at walthamstow central and brixton

 

[zwk500]

They're 60mph, right? Is that the fastest on the LUL system?

Yes.

Thought Victoria Line was 50mph (motoring to only 47.5mph.)?

The Metropolitan had/has 70mph sections but the S-stock can only do 62mph.

 

[GW43125]

80km/h (50mph) on the Vic. There's a section or two of 60mph on the outside sections of the Met.

 

[skyhigh]

Colton South is 70, North is 65mph.

 

[Class 170101]

The A Stock did upto 70mph but I think some said they had been reduced to 50mph many years before scrapping.
