Out if idle curiosity, at what point on the Heathrow loop does
westbound become eastbound?

Since the loop is unidirectional, surely at entry trains cease being
westbound, and at exit become eastbound? It's single track, so you
would not need to distinguish it from an adjacent one, would you? I'm
only guessing here.

We don't for internal use.

We use 'inner' and 'outer'


Up in Glasgow they use inner and outer circle for the Subway and the
Cathcart circle. The latter use 2Ixx and 2Oxx for the headcodes on the
Cathcart circle.

Unfortunately LU do so. I've heard references to "westbound Circle
Line" at High Street Kensington, referring to the inner rail which goes
south then east.

That is just one station not the whole line.

The main line use of up/down is not applicable to the UndergrounD so the
geographic system is more appropriate. I believe such useage predates Yerkes
involvement.

Yes, when I read it I did think that (a) up/down wasn't appropriate and (b)
what happened before Yerkes.

But

I also wondered about the Metropolitan given its' grand plans and whether
the line through Rickmansworth was ever up/down?

The brief history of the Metropolitan Line published in 1973 makes no mention
of the terms. Neither does the contemporary How the Underground Works in its
description of four tracking of the line north(!) of Harrow on the Hill.
Negative evidence I know.

Old BR sectional appendixes will presumably use the owner's
definitions between Harrow and Amersham/Aylesbury ?

Why not?

so the
geographic system is more appropriate. I believe such useage predates Yerkes
involvement.

I have no evidence to this effect.

In 1901 the District used Up and Down (Up was generally westwards), the
Metropolitan used Up and Down (Up was generally eastwards/southwards),
and the C&SLR used Up and Down (Up was generally northwards).
