Classic service reductions in HS2 phase one
Although slide #13 of Professor Andrew McNaughton’s February 2015 “Released Capacity” presentation was labelled “The Economic case for HS2: Assumptions Report: October 2013“, the diagrams on that slide do not appear in the Assumptions report. Furthermore, the indicative service patterns do not match (see illustration below).
HS2’s entire presentation is bogus, because the principal so-called ‘Do Minimum’ classic service patterns depicted are inferior to those which have operated on the West Coast line for the last five years. Since the Very High Frequency service started, the standard intercity service pattern between Birmingham and London has been three trains per hour, but HS2’s Do Minimum is ‘two, plus one running less than hourly’ (Figure 5-7).
The service enhancements on the Slow lines, and beyond Birmingham (Figures 6-3 and 6-6) could be implemented almost immediately. In no way are they dependent on, or a result of, capacity “released” by HS2.
