Dear Forum,

This is a request for pointers to rail cab footage (or similar) about 1.3 km SW of Leuchars -- footage that I hope might help me to identify some infrastructure on Fife.

More details below!

There is a large gas pipe (called "Feeder 13") which transfers gas between refineries on the east-coast of Scotland and refineries near Newcastle-upon-Tyne. It crosses both the Firth of Fourth (near North Berwick) and the River Tay (near Dundee). Between those sea crossings it traverses Fife (should I say the Fife Peninsula?) almost entirely underground. At some point in Fife it goes under the railway line that runs between Leuchars and Cupar. I believe the pipe crossing is approximately 1.3km SW of Leuchars railway station, and is within about 150m of the point I have labelled "A" on the attached image. I am interested to learn more about (a) precisely where the pipe crosses this railway line, and more specifically (b) how it crosses the east-west running river/stream which is about 200m north of the railway.

Quite frequently rivers/streams of the size of the one noted are crossed by pipes below the surface of the water (in fact even under the bed of the stream). However sometimes such rivers/streams are crossed by over-head pipes ... either using very solid self-supporting pipes on piers, or else using non-structural pipes supported on a truss/bridge structure.

In an aerial photo I have seen a tantalising suggestion of such an overhead pipe structure at the point I have marked "B" on the attached image, suggesting that PERHAPS Feeder 13 crosses that river overhead at that point. However, the resolution is no-where near good enough to confirm that's what I'm looking at, and so it's also possible it's a red-herring and the crossing is underwater somewhere else within ~500m of point B.

Hence I would be interested to hear if anyone can point me toward a section of cab-footage or similar (perhaps on youtube) which shows this region from a train . It is possible that such footage would capture the red/white utility marker posts which are often placed at field boundaries to help farmers avoid damaging buried pipes when working fields ... and such footage could also potentially catch a glimpse of the pipe crossing the river through a gap in the trees, if that's what it does.

It's much too far away from where I live to pop out and take a photo myself!

PS - before posting I did already try to find cab footage of this section of line on youtube. But either there is none or my search skills are not up to the task. I suspect the latter is more likely!

The structure you mention is marked on Ordinate Survey maps as a footbridge if that offers any help? Obviously it is very possible the gas line crosses using the bridge.

Have you looked at the open infrastructure map? If the link works it should be showing your gas feeder, you’d probably need to compare with another map or satellite view to get a comparison. Only shows it south of the railway, maybe a work in progress.

Thank you. I did not know that, so that's helpful info. But (as you rightly note) the gas pipe may or may not be be suspended from that bridge. Or if it isn't, then markers at field boundaries might indicate where it is as it must be somewhere nearby, so I am still interested in any footage. But thanks for the extra info.

Ha ha! The fun answer to that is that the main reason I'm interested is that I'm actually trying to improve the openintrastrcuture map in this area. A lot of the recent OIM pipework in that area is my work. So in this case it won't help me, but it is (or will be) the destination for any better info I get.

OK, not any help then. :D However there does seem to be a ‘shadow’ in the field south of the railway on Google satellite view that corresponds to the 45° kink in the line that puts the pipe roughly perpendicular to the railway?

For those of you interested in OSM -- I'm actually using Overapas Turbo rather than OIM to view most of the information I am collating and putting on OSM as it's a little more configurable. The best I have managed to work out in that area is as shown in the attachment with the black NS line being Feeder 13 known sections, and the circles on it being (usually) utility markers.

I'm not sure if it's much help given the purpose you have described, as OSM requirement for licenses from which data is obtained are strict, but there is a ArcGIS layer for SGN's gas pipeline.

Ah - yes. This would probably tell me (us/all) the answer, but any knowledge derived therefrom would not legally be permitted to go into OSM. So I have to be pure and virtuous and not follow the link. I should have said at the outset that I am looking for public domain primary sources compatible with OSM.

[ I have to say, though, that I am very impressed with the general level of replies here! If I wanted to plough the field and not damage the pipe, I'd be now well looked after! I am also impressed that SGN release that sort of info you mention, as when I have needed to dig foundations for extensions and have applied for information on danger to services through LSBUD, I've got the impression that (although the system works and does eventually give you what you need to know), it seems to feel a little like the utility companies don't want to tell you anything. However, mainly that's a false impression from a small sample set and only my local network operator (Cadent). ]
