Hmm, I'm surprised that given that there seems to be absolutely no improvement to the Cambridge services; no speed improvements, no frequency improvements for trains people doing en-end would actually use, no earlier/later trains.
I see 2 significant improvements.
One is the opening of Cambridge South station with a timetable that has all GN trains calling there, and with no significant impact on overall journey times. Kings Cross-Cambridge off peak is still 50 minutes 2tph. That's a massive win.
The other is that the new Cambridge-Kings Cross semi-fast peak trains are an increase in frequency, capacity and resilience. I'm not up early enough to use the morning trains but I will be using them in the evening. They are going to be particularly useful when Thameslink goes belly-up!
Further speed and frequency improvements are not going to be coming without major infrastructure improvements, because the branch has a lot of operating constraints:
- it is a 2 track railway for 23 miles Hitchin-Shepreth Branch Junction
- it has 7 intermediate stations
- it has 6 level crossings, 4 of which are AHB
- it has 2 significant intermediate speed restrictions at Royston and Shepreth
Cambridge already has one of the shortest overnight breaks in service. Going up the first Thameslink will be at 0451, the first "Cruiser" at 0542, and the last up train at 2351. Going down the first train will be at 0501 (that must be the earliest since the 0400 papers from Liverpool Street finished), the first "Cruiser" at 0554, and the last train at 0031. On a 2 track railway there has to be some overnight closure for essential maintenance, it is never going to be a 24 hour service. Most rail users in other parts of the country will wonder why you are moaning about these early starts and late finishes being somehow not good enough.
