    Short-term Pre-paid Mobile Phone SIM cards for UK Visitors

    Just be ready if you go into a mobile phone shop for them to be completely disinterested unless they can sign you up for a commission heavy contract.

    Old Dalby Test Track

    Well, Network Rail does have two other fully fitted ETCS locations available for testing, with the Heartford Loop also available. But eggs, basket, one, comes very much to mind on the ETCS implementations when one considers the publicly available knowledge.

    Island Line Class 484 Reliability

    Maybe would have been better to think about the wheel profiles rather than just do what everywhere else does… Although vivarailing the units rather than direct from LU with some careful conversion work might have been better for so long as the 73TS is in service

    Merseyrail mandates that Trainline tickets must be printed out

    Maybe if we just had a national ticketing system rather than the fragmented mess that we’re heading into / have now…?

    Old Dalby Test Track

    You mean it’s not trying to fit the equipment to the locomotives…?

    Short-term Pre-paid Mobile Phone SIM cards for UK Visitors

    I'd recommend GiffGaff, but it's potentially challenging to find a physical store selling their SIM cards, I think Morrisons carry them. But as a provider, they don't do any attempts to lock you in, other than providing some loyalty discounts. FYI. I would very much not recommend using public...

    Doncaster Sheffield Airport to reopen?

    And with the flight number limits at AMS, it's unlikely that new routes on risky airports would happen. I'd much rather see them try to move back into EMA again, the FlyBE route from there was popular.

    EMR Class 170 updates

    Why is it, pray tell, that trains need WiFi?

    WCRC loses judicial review in High Court

    How many times has a whole brand new fleet of trains ordered by the DfT been banned from running on the network?

    Class 43 disposals

    Only if they were pulled out of the skips or hidden when the previous inhabitants pulled out of the site.

    Differences between TPWS, ATP and ETCS

    Which is exactly why it is what the UK would do. Bearing in mind that locomotives built almost entirely to European specification, were until recently still required to have (entirely pointless) adaptation devices to make them work with the very European ETCS equipment destined to be fitted.

    2024 Tube Stock (Siemens Inspiro)

    TRC666 has buckeye couplers with a different centre pin position on the underframe so that changes how it's pulled, held and stabilised round corners. 1972TS has bar mounted jumper cables and hoses that can cause problems on tight curves due to the mounting height of the tray coupler, when...

    Potential up to 2,000 job losses at Alstom Derby

    This will keep happening until the government realises that our current method of procuring rolling stock is simply broken. We do not need four assembly plants in the UK for our railways.

    The Two-Coach Voyager

    Compressor is the key bit of equipment on Voyagers, but there's other less well known bits too, not within my current knowledge to know what they are any more, not worked on Voyager in a loooong time.

    2024 Tube Stock (Siemens Inspiro)

    The timing loops on SSL were adjusted and the TrackLink III tags used to tell the train how hard it can drive if I'm remembering correctly.

    SWR Class 458 to be retained

    For info, enhanced overlap protection for TPWS was termed TPWS+ by Network Rail in a press release back in 2004. This term is carried on into RIS-0775-CCS Issue 3 as a “previously referred to” in the guidance notes. This is for when multiple OSS loops are provided

    SWR Class 458 to be retained

    Enhanced TPWS is defined from GE/RT8030 Issue 4 onwards (Now RIS-0775 and GE/RT8075). This is defined by the RSSB as Enhanced TPWS. The 4 comes from this being in force since Issue 4 of GE/RT8030. If you want a definition of Enhanced TPWS, check Appendix F of GE/RT8030 and later issues of the...

    2024 Tube Stock (Siemens Inspiro)

    Until new signalling, re-acceleration rate is one of the parameters of the signalling system so any changes to train performance would need re-signalling of any speed control on approach loops. (Among many many other things.)

    SWR Class 458 to be retained

    Point of correction, it gives a verbal indication that it's passed it's POST, not that it is in fact operational. You can have the AWS Isolation Switch (not to be confused with the AWS Isolation Switch pre Enhanced TPWS) in the isolated position and it will still annunciate that they are both...

    2024 Tube Stock (Siemens Inspiro)

    Not to be purely argumentative. But you're wrong. In addition to it not being the same size. There are some significant issues with depot space on the line that are not simple to solve. London Road depot cannot accept any additional length on 1-4 road, and if one did any form of refurbishment...
