What are these "yards" things? In my day if it wasn't miles it was chains.

Footbridge at Cheshunt earlier today.

Footbridge at Cheshunt earlier today.

And I'd say it still ought to be in Chains ( - officially; however archaic that may appear: Well I'm pretty sure it would've been chains up to last year at least, anyway).

Don't know when this plate went up, but grateful it isn't metric

This bridge was put up over Christmas and is marked in miles chains...

Presume it's the first one to be put up between 107 and 108 (i.e., suffix 'A'), but wonder what the 'D's for?

There is already a 107D i believe.. I've not really worked it out yet.

Doncaster or Darlington area?

Bang goes that bit of logic

We live in a former railway property next to the ECML. I have had recent communications from Network Rail concerning drainage and fencing, and all their paperwork refers to miles and chains. Quite handy really as there is the 31 3/4 mile post at the end of the garden so it is easy to work out the distance along the boundary from that, if the paperwork was in Km and metres I would be totally lost.

Not necessarily.
Darlington area, and quite possibly Doncaster area if north of Shaftholme, as ex-NER territory, could easily have a different number series for ECML bridges.
The ELR (Engineer's Line References) codes for long routes are often sub-divided these days); e.g. ECM1, ECM2, etc., as seen in the photo in RP's post of yesterday (not sure how long this practice has been in place).

ECML mileages count from zero at KX to York. Then from zero at York to Newcastle, zero from Newcastle to the border and from zero at Edinburgh to the border.

ELRs came into general use in the late 80s prior to that a numeric route code had been tried.
Can be easily found in Quail maps.

Most ELRs are fairly easy to work out.
Generally an initial for a junction or station at each end.
YMS - York - Malton - Scarborough.
HBS - Hull - Bridlington - Seamer
TJC3 - Tapton Jcn - Colne from Normanton through Leeds West to Skipton North.
The number is in place when the route has been subdivided as stated earlier like ECM 1,2,3,4,5,

As for how long the practice of including the code on bridge plates.
I seem to remember seeing my first one in the mid 90s on Leeds North West electrification works.

As for the use of chainages this is definately because all structure records are recorded in Miles, Chains and yards. I think Links have finally disappeared though.
Unless that is the structure is an Overhead Power mast then it is located in KMs.

Agreed, 52A. But do the bridge number series start at the same zero mileposts I wonder. I don't know.
Oh for access to GEOGIS; - Sorry, CARRS!

There is also an alpha-numeric system in internal use called 'Line Of Route' (LOR) principally for non-engineering purposes I'd think, and is found in such as Sectional Appendix Table 'A' line diagram page headings and Weekly Operating Notice route sections; e.g. LN101 (the modern NR 'LNE' Route), and EA1310 ('East Anglia' Route).
Is that anything to do with the numeric code you refer to? Or is it the method used in the 1947 LNER Sectional Appendices?

... for the ECML electrification (including the earlier GN Suburban elec'n), and presumably other relatively modern schemes, yes.
But to be fair this isn't always so everywhere. For example the London - Liverpool/Manchester sections at least of the WCML elec'n, I'd have thought would be numbered imperially, and the early GE overhead structures (e.g. Liverpool Street - Southend Vic., are definitely No.'d in Miles / nnth structure in the mile.

Is the bridge the new Hitchin flyover and the D refers to one of the at least 4 spans?
