What he did not say is that this journey time is achieved by just one train each day, in one direction only. Further, he did not say that this train achieves the time of 72 minutes by not stopping anywhere, so that if this fastest time were to be made standard, Birmingham International, and Coventry would have no service to London at all. These other facts are a significant omission, probably deliberate, on his part.<br /><br />In the same article, Gilligan also claimed that HS1 had made classic services in Kent worse. This doesn't actually stand up to analysis.<br /><br />I have studied Table 207 (the South Eastern main line through Ashford and Tonbridge to Charing Cross and Cannon St) and Table 212 (the Chatham main line to Cannon St, Victoria and Blackfriars), for the critical commuter sections towards London from Ashford and Chatham respectively, in the morning peak hour. <br /><br />In no case can I find a station that has lost services, whilst several have gained:<br /><br />Increase in AM peak hour services, 2011 over 2007<br />Ashford 2<br />Marden 2<br />Sevenoaks 1<br />Chatham 1<br />Rochester 4<br />Meopham 1<br /><br />In the case of Table 207, the two HS1 services per hour from Ashford are completely additional to the 2007 case. In Table 212, there is a net gain of one train, as two additional HS1 domestics net off against one fewer Victoria train, which is reasonable as Victoria and St Pancras are equally good terminals to access the West End whilst the key Cannon Street services have been maintained.<br /><br />Far from trains being slower overall, in Table 207 one is slower by 2 minutes whilst three are faster by up to 4 minutes. In Table 212, there are three trains slower by 3 minutes at worst, but five faster, one by as much as 12 minutes. <br /><br />The fact that trains are in many cases now faster than in 2007 is explained by diversion of Eurostar trains away from the classic routes, removing a conflict between fast through trains and the slower trains that have to be planned to follow them. In particular, the train that has been accelerated by 12 minutes appears to do so, in the absence of Eurostars, by being able to use the direct route to Victoria via Penge rather than the secondary route via Catford.<br /><br />So if anyone wants to draw parallels between HS2 and HS1, they could reasonably conclude that, without fast through trains sharing the classic routes:<br /><br />• intermediate stations, which in the case of the WCML would mean places like Milton Keynes, have gained services;<br /><br />• trains have generally become faster.<br /><br />On the latter point, the fastest London Midland train from Milton Keynes to Euston now does the journey in 41 minutes, whilst others making the same stops are between 3 and 5 minutes slower. This results purely from “pathing time” incurred following slow trains when unable to use the Fast line, or through waiting to join the Fast line so as to fit in with the fast through trains that will transfer to HS2.<br /><br />William BarterWilliam Barterhttp://www.williambarter.co.uknoreply@blogger.com
