The whole HLOS this time around is very thin, expectations were that enhancements would be reigned back in but the growth predictions are very cautious, as they will have been under-pinned by The Treasury's forecasts for Central London and other cities employment they don's suggest a very healthly time for the overall economy in the short to medium term.
London growth at only 4.9% (for the three peak hours) between 2018/9 and 2023/4 compared to the 22.1% forecast for 2013/4 to 2018/9. Undoubtedly the latter was knocked off course by Brexit and has been reflected in the figures for the last year as mentioned by others.
The detail throws up some interesting nuggets too, with zero growth forecast for services into Fenchurch Street, (with even a slight drop in the high peak hour!), compared to an 11.85% increase in growth on non-Crossrail services into Liverpool Street. Goob job then trying to make the business case for the contracted extra units on c2c when growth is forecast to be zero! Odd especailly as there's undoubtedly some competition between the two routes to Southend at least! The Liverpool Street increase is predicted to be the highest in absolute terms of all London routes, though services into Kings Cross (non Thameslink) have the largest percentage increase at 21.7%. In some respects some of the figures look more like what capacity increase has been contracted by franchisees rather than forecasts, which surely is the answer not the question and a bizarre adoption of the policy of and provide then predict!
There's no doubt that both Crossrail and Thameslink skew the absolutes and that delays to delvering the full services on both routes until CP6 may be muddying the waters for simple comparisons however.
The non London forecast is similarly modest at 2.7% compared with 16.0% for the five years going forward back in 2012.
All the above must throw up many questions for the TOCs and owning groups not least if their own forecasts are now out of line with the DfTs and the Treasury. No wonder there are apparently queues for reviews of franchise terms at Gt Minster House?
