Mileages

Last update 5 May 2023

Additional information is always gratefully received, whether entirely new records (particularly historical records) or information to fill in gaps or correct errors, via the contact link under the Miscellaneous entry in the navigation bar above. Thank you.

Mileages are given in the form miles.chains unless stated otherwise. Figures prefixed with ≈ are approximate, those in parentheses are not on this route but are given for reference. Reference to 'start'/'end' of an asset are as read down the page.

MOA Mountain Ash deviation

Original measure
   0.00	junction with ABD (19.59)
   0.23	MOUNTAIN ASH
   0.38	junction with ABD (20.16)

Measure sometimes used
  19.59	junction with ABD
  20.02	MOUNTAIN ASH
  20.17	junction with ABD (20.16)

Measure used briefly in 2022 documentation in error, soon corrected
   0.00	junction with ABD (20.16)
   0.23	MOUNTAIN ASH
   0.38	junction with ABD (19.60)

Note that a 2022 signalling plan suggests that MOA applies to the down line only.  This does not correlate with mapping evidence that shows a significant deviation from ABD, particularly at the low mileage end, to the up (northbound) side of the line.  The Sectional Appendix to the Working Timetable applies to both lines.
