About Elizabeth line speeds on the GEML

[bluerun46]

The linespeed on most of the GEML slow lines is 70mph. Is there a reason why trains do not routinely hit 70 on the particularly longer stretches of track? I find trains run at around 50 instead, maybe 65 if the train is running late.

On another note, there currently appears to be a temporary speed restriction between Manor Park and Forest Gate. Anybody know why?

Because there is no real point to driving flat out, there is enough padding on the service

There aren't many sections we can hit 70...
But we can do so between Ilford and Seven Kings, Chadwell Heath and Romford, Harold Wood and Brentwood. All both directions. That's about it really. I would say I routinely hit 70 leaving Chadwell Heath and Harold Wood, and perhaps about 60 leaving Ilford as this section is shorter.

No idea why there is a 20 mph ESR over Forest Gate Junction, but what I can say is that it's highly annoying!

Especially as it briefly went upto 50, before returning back to 20 which almost caught me out!

Reason given is track - rail defect.

Guesswork - Possibly a defective crossing which can be slow to obtain. I’d also guess that it’s complex to get access/possessions there as it presumably closes the route to/from the LTS so needs the T&H to be clear, and maybe needs the UM closed or fenced off too??

Good luck hitting 70 between Ilford and Seven Kings start to stop I would say.

Some weeks of all line closures between London and Shenfield coming up in February.

I hit 70 pretty frequently in both directions (about 30% of my trips) on that stretch with a good enough coasting session in-between the acceleration and braking. But I am still more likely to do about 60 as there isn't really any need to do 70. But 70 is the line speed so nothing wrong with taking it to 70.

Especially as it briefly went upto 50, before returning back to 20 which almost caught me out!

The ESR warnings are set up very badly too, and the reminder board at Manor Park is equally as badly placed. I wish when they change the speed of the ESR, they would also move the ESRs warnings slightly (it supposed to be service braking distance after all and that is clearly different for a 20 and a 50).

 

[Horizon22]

The main issue is the amount of stops and nothing runs semi-fast (outside of disruption) on the GEML. Obviously accelerating and decelerating every 3-4 minutes means you won’t hit the top speed often.

I’d say the best chance is between Chadwell Heath and Romford and Brentwood to Harold Wood as some of the longest stretches.

First weekend is the last one of January and then rinse and repeat for 4 weekends.

Still not a guarantee of access if the repair at Forest Gate conflicts with other jobs, stops the movements to/from site needed by others, or……

And if access is possible, all replacement components need to be on hand.

It’s never straightforward!

No it never is unfortunately.

I remember sitting at Gidea Park in the mid eighties and it seemed the trains used to come through a lost faster. Have they drastically lowered the speed or did they just seem a lot faster back then. I'm talking about the 321s and the big iron to Norwich.

Well the mainlines are 90mph. Only the electric lines are 70mph.

At Gidea Park station, the Electric Line is 40mph towards Shenfield, and 50mph towards London.

I think the ruling speed of 70 mph on the electrics dates back to the class 306s which was their top speed ( even though wikipedia shows 75).

We were also told it is due to the signal spacing being a lot closer on the electric lines between Bow Junction and Harold Wood. eg. between Seven Kings and Chadwell Heath there are 9 signals on the electric lines (including platform starting signals). On the mains, there are 3.

Quick update on the 20mph Emergency Speed Restriction in the Forest Gate area. It has been extended now from Forest Gate Junction (5 miles 68 chains from Liverpool Street) to Maryland (4 miles 31 chains). Hence a few delays on the Up Electric line this morning as was previously just 8 chains in length.

Hopefully removed / reduced back soon.

big iron to Norwich

I have to ask about this?

I worked on the railway back in the 80s and they would call the blue locos big irons.

The ESR is still in place between Manor Park and Forest Gate after a few months. Any update?

Planned rectification should be late May or early June.

Cheers. I was only wondering that on Friday as I drove past on the UM.
