Without phase 2a, HS2 capacity will be limited by the number of trains that can fit through the flat crossing at Colwich. During the day, throughput will be limited to around 10 tph or less: 6xHS2; 2xWCML (one fast, one slow); 2xfreights. The constraint comes from the WCML being a mixed traffic...

Two recent developments to report: The budget documentation yesterday states “The government is working with Lendlease – the Euston Master Development Partner – and the London Borough of Camden to identify parts of the station site for early release and development in coming months, and...

Transport minister Mark Harper claims that "We’ve learned a lot from the electrification of the Great Western line.” Is there any evidence that this is the case? What lessons have been learnt, and where might these have been documented? Have these been incorporated into later electrification...

Following on from the Manchester Piccadilly thread, where in Liverpool could take 400m platforms? These would be needed to handle full length HS2 train sets, even if the approach were on existing lines...

With the ECML closed between London and Peterborough, just how busy is the MML likely to be today, please? I was planning to travel to London returning around 2000h. Will MML trains to Nottingham be standing?

One of the criteria for new housing is the provision of adequate public transport links. Indeed, the rationale for East-West Rail is to enable large developments at places like Cambourne. Labour is promoting the idea of New Towns to solve the housing crisis. Rather than building new lines...

RDG have ordered 10 Class 93s (4MW on AC; 1.3MW on diesel; 290kN starting Tractive Effort); GBRf have ordered 30 Class 99s (6MWe; 1.6MWd; 500kN). Under the wires these are very much more powerful than diesels like the Class 66 (1.8MW at the rail; 409kN). DRS already have 10 Class 88 (4MW...

I'm trying to understand the actual capabilities of heavy freight locomotives like the Class 66. Wikipedia suggests a starting tractive effort of 409kN, and 260kN continuous at 15mph. Are these figures achievable in practice? 409kN is 40 tonnes, which seems a lot for a locomotive with steel...

If HS2 Phase 2B is not going to be built, then capacity to Manchester will be severely limited by the number of trains that can get through Colwich Juntion and Stafford. The only way to increase capacity to Manchester is to run longer trains. This is how I would add 3 x 400m platforms at...

The Jan 2024 update from HS2 says that "We are also working closely with Network Rail to develop options that enable HS2 trains to reach Nottingham and Sheffield via Derby and Chesterfield on the Midland Main Line." This could be a connection from the stump of the Eastern Leg, or perhaps some...

I'm interested in what timetable will be possible after Sunak's HS2 decision. If it gets built, HS2 Euston will have 6 platforms and no grade separation in the throat. How many trains per hour will that enable? How many tph could reverse in the centre platforms at Old Oak Common? Given that...

Another crayon question for you. The safeguarded route for Crossrail 2 is shown on this map: https://cr2.maps.arcgis.com/apps/webappviewer/index.html?id=21a7f72dfd0c443db5733bd81a707a67 Looking at the section in central London (Clapham Junction-Victoria-Euston), could this corridor be built as...

Hi. Can anyone help? Is train TGV INOUI 2356 the same train as TGV 9576? They both leave Strasbourg at 1044h and arrive Paris Est at 1231h. I'm asking as I want to join the train at Karlsruhe on 14 August (0953h), but the DB website calls this train TGV 9576, whereas my interrail reservation...

This thread is to discuss news and developments of the Hitachi battery intercity train for the UK market, which I understand is being developed by replacing one diesel pack on an 802. So I suggest we call it the 802B, until we get a more official name. Here is the Turntide press release ...

A large part of the cost of new electrification comes from having to rebuild bridges to provide adequate clearances for 25kV OHLE. This is my attempt to specify a DBEMU based loosely on the 80X family that would be capable of handling gaps in electrification and therefore allow lines like the...

DRS already has 10 Class 88s (317kN tractive effort; 4000kW on the wires; 700kW off). ROG has taken delivery of the first class 93, with 30 on order or under option (290kN; 4600kW & 1300kW) GBRF has ordered 30 Class 99s (500kN; 6000kW & 1600kW) and more bimodes may be ordered over the next few...

When HS2 phase 1 is delivered, trains will take 42 or 49 minutes (not sure which) to get from Curzon St to Old Oak Common, with direct connections onto the Elizabeth Line and the eventual promise of direct trains to Euston. This is puts it well into commuting territory. How practical will be...

The NAO is saying that Euston will now cost £4.8 Billion, and that's at 2019 prices. God knows what the estimate would be at 2023 prices. And presumably the tunnels from Old Oak will cost a couple of billion on top of that. (2x8km @ £100m/km or more)...

If the Bedford-Cambridge section of East-West Rail gets cancelled, I was idly wondering how much use a single-track South-East chord at Manton junction would be? It would allow: Freights from Southampton and the South Coast to access Peterborough and the East Side of the country without going...

The CAVForth autonomous bus trial has just started test runs with volunteer passengers, in preparation for full public service later this year. https://www.busandcoachbuyer.com/first-passengers-board-stagecoach-autonomous-bus/ I understand the buses operate, for now, with a back-up driver in...
