When Up Becomes Down

[CyrusWuff]

Going back to the original question, looking at the relevant Sectional Appendices from the Network Rail site, the lines are Up (Southbound) and Down (Northbound) Moorgate between Kentish Town Junction and the route boundary at 0m66ch (measured from the former Moorgate Junction), where they become the Down (Southbound) and Up (Northbound) Snow Hill.

Just to confuse matters, Marylebone is located at 205m 77ch (from Manchester via the GCR!) but the departure line is the Down Main and the arrival line is the Up Main, as you'd expect.

* its the up and down st helier.

Ah yes, so it is, I knew my memory was playing tricks. Thanks for the correction.

Standing On the Anglo - Scottish border, it is 'up' northwards, towards Edinburgh or Glasgow, and 'up' southwards, towards Newcastle or Carlisle.

On the ECML, the change is on the border, though the nearest reference point is at signals EG 402 and 403 at Lamberton, a few hundred meters north of the border.

On both the ECML and WCML, the line designations remain unchanged across the border and regional boundary (so 'Up' is towards London, even in Scotland). There is a change of mileage on the ECML though, with the mileage reversed north of that point - zero at Edinburgh Waverley, and decreasing in the Down direction.

Things might change again when one ROC (Three Bridges) controls the entire area from Brighton through London to well down the MML and ECML.
