How many Sand Drags still exist around the country?
On the Heritage side there is one at Goathland NYMR and there used to be some on the approaches to Goole Swing Bridge. Are they still there?
Are there any more?

Quite a number still exist on the mainline.

Britannia Bridge (between Anglesey and the mainland) - sand drags at both ends of the single line.

Hyde Junction just east of Guide Bridge, which is single lead. There's a sand drag on the Down Woodley Branch, presumably installed in the wake of the Newton and Bellgrove accidents?

Macclesfield, at the south end of the Up & Down Platform line (for platform 3).

Goole Bridge ones was removed about 15 years ago approx. when TPWS arrived on the scene. The existing ones was well and truly life expired. So removing them took out two sets of points as no longer required and now trains stop another signal back from the bridge when it opens to river traffic.

There's one on the Up & Down Westgate Curve between Wakefield Westgate and Kirkgate stations, located on the approach to Wakefield West Junction.

Island Line has one at Smallbrook, protecting the single line.

A few on the underground, as far as I know all in sidings though.
I was going to say the same, there’s loads on the underground, in both open as well on tunnel sections.

There must be loads, there's one at Eastleigh, one at Bordesley just randomly off the top of my head.

A couple I can think of are St Margarets Up Passenger Loop protecting the Up Main towards Richmond, and the London end of Farnham Depot Reception Road protecting the Up Alton. Pretty sure there's one at Rye protecting the single line towards Ashford as well. Probably plenty still out there.

Platform 4 & 5 at Southport - they're there to protect the station building, hence why the other platforms don't have them.

Thanks again,


We have them. Just that I have only known them as a "sand trap" so I was confused as to what a "drag" was. Out of "interest" what would be called if the trap points took you off a bridge instrad of into a sand drag :/

Death trap? :)

I always looked at those points and thought you would go head first into the concrete. Literally a 30 (ish) foot drop with a 2m run off. Sod having a SPAD there. Tea and biscuits with *God.



*Satan or other available Deities.

I believe there is one at Bradley Junction near Huddersfield on the end of the single line from Bradley Wood Junction.

Yes there is. Was installed when the curve re-opened* in 2000.

*= when I say reopened, I'm not sure the curve was ever officially closed. It had been used for diversions in the mid to late 1980s but had since become engulfed by greenery including a number of saplings sprouting in the four-foot. Once the decision was made to reactivate the line, ripping it up and starting again was pretty much the only option.

The Hyde Junction example was installed after the collision there, resulting from a start-away SPAD by a train in the platform.

There’s a few that I think I know of:
Kennet Bridge Loop (nr. Reading) has a sand drag at the country end (down direction, towards the station) of the loop, protecting the Down Relief.

Swanley Platform 4 (Down Chatham Slow) has one at the country-end (towards Farningham Road), protecting Swanley Jct.

Exeter St Davids has one on the Down Waterloo approaching the station from Exeter Central, protecting what I think is called Exeter St. Davids Jct.

There's a drag (well, actually, more of a ballast hump, it doesn't have the boarding which a true sand drag has) at Chinley North, installed after a couple of runaways, one of which resulted in the withdrawal of 47089 and a Class 31 which hit the errant 47 after it went through the traps and fouled the main line.

After another incident (involving a 37 I think), the traps were moved further back to allow room for a makeshift drag.

Historically, there was an interesting example at Valehouse on the Woodhead Route. This was situated in the Down Goods loop and was interlaced with the loop track, before rejoining it via a set of trailing hand points. The entry to the drag was controlled from the box, so that a runaway could be diverted into it deliberately, to give it a chance to stop.

There used to be one just the Great Yarmouth side of Carrow Road Bridge at Thorpe Junction, Norwich. Don't know if it's still there though, I guess it will have disappeared with the electrification and resignalling.

Approaching the buffers at both Bognor and Littlehampton, there is perhaps half a carriage length of sand/soil/detritus which likes to a depth of perhaps 10cm above the rail head. Do these count as sand drags, or just neglect? I've always wondered why we don't approach to 6ft from the buffers like we do in all other termini.

not a sandtrap, but the bay platforms at Lancaster have a curious arrangement with an inner spring-loaded pinch rail which would serve the same purpose. Also the railheads have a raised zig-zag pattern on the surface presumably created with welding equipment - I assume to try to scrape sliding wheels?

There was a previous thread on the sandtraps at https://www.railforums.co.uk/threads/railway-geology.143118/
Mainly discussing this interleaved one on the climb to Bincombe tunnel

That sounds like electric depression bars - an electromechanical switch linked with the track circuit to reinforce operation over the last 60' or so where the rails aren't as polished by the wheels, and the zig-zag pattern is stainless steel weldstrip which has replaced the bars, but they've not been removed (not uncommon, they are heavy pieces of kit) .

Here's a photo of the depression bar in the bay at Stoke-on-Trent. Train detection is by axle counters so the bar is redundant, but there is no need for the stainless steel strip.

Not sure if its the same or not - from memory they're on both rails and at rail height, as if intended to pinch the back of the wheels, though I guess that could be for electrical continuity
