Attached to various sleepers at High Street Kensington there are a
number of data plates. Presumably these can be found all over the
system. There are two main types (plus some odds and ends).

One sort has a large arrow and gives the name of the station and the
track. There's one at the start of the platform, and others along it
with relative distances marked.

The other sort has a large arrow as well but has various items written
on it. Here's an example:

R C C.G.
305 30
$26 $
STR NIL + 6m

where the $ is a small upwards-pointing arrow and the 26 is smaller than
the other text. It also had, in much smaller text below it:

DISTRICT EB KM45.094
MAR 94

Two others have instead:

R C C.G.
987 10 10/13
$10 $10
STR NIL 1/1000

R C C.G.
6250 NIL
$15 $
1119 10 + 5m

Can anyone explain what this means?

I'd guess the distance is based on Ongar kilometrage.

Yes. That's the bit I *do* understand; it's the rest that I'm looking
for more information on.

I'm thinking that those letters are indication of some imperial measurement
of length. R is probably Rood or Rod. 1 Rood is 3.77 metres, 1 Rod is 5.03
metres. C could be Cable, of which one is 185.31 metres, or Chain. There are
two types of Chain, Ramsden and Gunter, 30.48 and 20.11 metres respectively.
C.G. is likely Chain Gunter. Arrow could be distance to some certain point
from that plate.

Extremely unlikely. Distances on the Underground are done in metric,
using km from Ongar as a reference system. Nobody uses roods or rods any
more, cables are nautical, and while mainline railways use the 22 yard
chain, LUL does not.

Does not now but were all the old markers (presumably in miles and 22 yard
chains) removed when kilometrage was adopted?

If you know where to look you can occasionally see the old mileposts.

However, that's irrelevant to my original enquiry, which is about
*modern* data plates. Given that the plate says it's 54.132km (from
Ongar), claiming that it's using roods and chains is a complete
nonsense.

Does nobody here know what these plates are actually showing?
