Bring back London Transport (and British Rail for that matter).


And stop talking in metric, last time I checked we used MILES in this
country. At least that's what's on the dial of every car speedometer
I've seen lately.

Many vehicles have a dial that shows both or a display that can be
switched.

It was London Transport which recalculated its route measurements to
Kilometres back in 1972 .
Ironically they chose Ongar as the 0 datum

I think they chose Ongar because it was the furthest east.

which means their measurements start on a line that was closed and is
now no longer theirs

It's not the only disappeared datum. Road miles from London were
measured from the Post Office near St Pauls (the tube station used to be
called "Post Office") because postage was originally calculated by the
mile.

The site is now occupied by a merchant bank, and the A1 no longer goes
to the door, but has only been truncated by a few hundred yards.

The old measurements as miles and chains sometimes had oddities due to the
different paths of ownership some sections had passed through over the
years , eg Richmond to site of Studland Road junction were measured from
Waterloo due to the former LSWR then Southern Railway ownership of that
section.

You will be pleased that the Underground still use mph for speed
indications though and even the S stock speed indication is in MPH.
Hopefully they won’t change it or they will be wanting to tow the whole
lot back to Derby again to change it.
