What is this fastening called

[jacko2327]

Hi I have come across this fastening and wondered if anyone could tell me it's correct name.

Pandarol Clip of a sort.Got asked this on my guards course in 1985.How I knew at that time I will never know.I think it was more of a guess.

Enter it into google images and a lot of these come up.

Pandrol not Pandarol

Thank you.Oh yes google corrected me as well.

Are you sure it's a Pandrol clip? It looks similar but not quite the same as any of their clips

 

[jacko2327]

I have looked on pandrol website and nothing on there. Looks similar to the e clip but has an extra bit that comes back under the housing which has clearly been made especially for these fastenings.

Correct me if I'm wrong but is this image from a laser track survey piece of equipment, or a rail head camera?

I did say "of a sort".

 

[DaleCooper]

It looks a bit like one of these, broken in half and mangled

I'd not a clue what PLPR meant, but the following thread throws some light on it

I think its one of the original 60's design that has been bent out of shape. (the design came in left and right sided options)

Similar picture of a vintage pandrol that has been incorrectly installed,

And what it should look like.

i.e. the arm should be resting on top of the metal not underneath it and its been installed back to front.

Those are 2 different styles of pandrol clips, e clips at the top and 401 at the bottom.

Pandrol clips weigh a ton (well, feels like it), in bulk bags had to count around 1800 of them, separating L and R ones last month.

Spot on.

The 401 can be knocked in with a hammer, the e clip needs a pan-puller to insert.

If you enjoyed that I have a bag crimps I was going to give to a Graduate that you might enjoy

I'm wondering if the aspect ratio of that image is wrong, when you stretch horizontally it looks a lot more like a Pandrol clip.

It still looks wrong the nylon is a funny shape and the end of the clip is not usually turned under the housing.

True but I wonder if someone has attempted to fit a reject clip, where there's been a manufacturing error, and put it in the wrong way. You sometimes get rejects in batches of pressings and forgings, I've seen things like washers without holes and screws without threads.

 

[Joseph_Locke]

I'm with Trog; the housing has a space to take the tail of the clip, and there's too much clip as well. I shall consult the oracle and report back.

 

[WatcherZero]

I still don't think its by design, it looks deformed where it passes under, its also twisted In the centre. If it was fitted to the left rather than right it would look correct.

I've done some extremely odd stuff on overtime, but never thought I'd find myself covered in muck in a corner of the shed counting everything from pandrol clips to spare pantographs

But Pandrol clips and their nylons are fascinating, there are so many different ones to collect.

The thing that is wrong with this is not that the clip is the wrong way round, but that it is the wrong sort of clip.

Most Pandrol clip cast iron baseplate with just a few exceptions, are supposed to be used with the older PR series clips, baseplates Pan1 to Pan5 using a smaller size clip PR427A or the LH PR428A, Pan6 up and the various V baseplates using the larger PR401A or its blue LH version the PR402A.

The e1809 shown and the other e series Pandrol clips are for use on steel and concrete sleepers, and a few baseplates that generally also take a nylon. These baseplates are often made from the stronger spheroidal graphite (SG) cast iron rather than the standard grey flake type.

There is around 3/4 of a mile of this fasteneing type. ECM1 UP MAIN around 117m 440y

I found a better illustration of the Stedef DSA fastner.
It's from this presentation (a hefty PDF)

Apologies for digging up this old thread and taking it slightly off-topic, but recent observations have made me wonder something and it wasn't worth starting a new thread.

I live alongside a line that is currently closed for five weeks for upgrade works. Small excavators are among the equipment being used, and as they run up and down the track on tank treads (rather than their railway wheels on the track, which they also do) some of the Pandrol Clips have been displaced and are no longer clipping the rails to the sleepers.

Which lead me to wonder how many Pandrol Clips can be missing from a rail before it starts to become liable to spread under the weight of a passing train?

I'm guessing that there is an inbuilt margin of error, and that a few missing or displaced Pandrol Clips isn't going to be too much of a problem in the circumstances. I'm also assuming that the speed and weight of trains plays a major part.

As I watched a procession of six fully-laden engineering trains use the track last night, it made me wonder how many Pandrol Clips could be lost before I find an unexpected limestone rockery has appeared below the kitchen window! (Yes I am joking, but we all know these things do happen occasionally!)

What are the guidelines?

It'll be in TRK/001 somewhere, but five missing in six isn't fatal at low speed, provided all the five unclipped sleepers are still there!

When installing long welded rails in the old days we used to run them straight off a LWR train pulled from underneath them, and put them straight into their finished position on the track the train had run over seconds before.

To achieve this, the old 60ft running rails had to be completely unclipped BEFORE the train passed over them. The rails were then tipped out and pads and insulators repositioned, all while the new rails were inexorably lowering towards the sleepers.

What price health and safety those days?
