Seems the focus on getting the rural services back to normal may have slipped. Bittern line trains still routinely up to 30 mins late or cancelled.

There was rumour that some work was carried out in good faith on the level crossings even if the root cause is still debatable. Does anyone know if there is still work ongoing to improve or is the service permanently degraded?

Oh that's just down to a points failure at Cromer this afternoon/evening. Everything else is almost fine now. Just a coincidence.

If not connected to the internet then W2K is a very stable OS, yes it's old but then again it's also tried and tested, and needs minimal hardware specs compared to more modern OS's.

Need to remember it's unlikely to be win2000 as we run it, the kernel will be the same but it will be stripped down and only run the pis

Of course, you don't want the drivers playing a bit of 3D pinball whilst they are driving :lol:

That would make some interesting headlines

There are a lot of Windows Embedded things, Pendolinos and Voyagers use it. Also the Windows NT kernel use by Windows 2000 is still used today in Windows 10.

I'm not sure there is an embedded version of Windows 10 anyway, it's a beast of an OS. Mind you it could of course be running the much more stable Linux off a Raspberry Pi or similar, though that requires more technical expertise to set up.

It is now Windows 10 IoT Enterprise (https://en.m.wikipedia.org/wiki/Windows_IoT)

I use the line regularly and its every day, RTT shows this as a sea of red for the last 2 weeks. So if everything is fixed the new level of service means I will regularly get free travel from delay repay?

First sheringham to norwich is delayed and the knock on starts to later services.

Is there any restrictions for level crossings or is this just performance of the 755's on the line now?

Dont get me wrong really want the new trains but if they miss my connection at Norwich each day then I'd prefer a 156

The 755s are recovering time through acceleration in a way the 156170s never did. Network Rail still have a 20mph ESR in place for all trains from Worstead to Tunstead Market St and this will remain until signalling alterations are made. Until this time the loss of a few minutes has to be expected.

Makes sense but the delays are likely caused by hold ups as services pass at north walsham. Hope this gets lifted soon. Just watched a 755/3 work the line this morning.

Although it is probably using Windows Compact Embedded.

Why not just use Linux? Stick CentOS or Debian in there and you're good to go for ages. All the software is custom built anyway.

Absolutely, and needs minimal hardware. Reminds me of the US Navy Destroyer which was left dead in the water when all the networked Windows NT Servers went Blue Screen of Death simultaneously.

But seen this so often, recall that the PIS system on the Central Line was programmed with an 8-bit paint program from DOS when everything else was going 32-bit.

Seconded, but this is the railway...

Just to mop up all the Windows 2000 chat, the systems on the Stadlers use Linux.

Thanks, whatever system the PIS runs on @dk1 has stated its a pain in the ***e to use!

Which is a shame as the displays themselves are nice

Abbo · 2 Jan 2020

I am contemplating a journey from Sheringham to Lowestoft next week but because of the fragile state of the Bittern Line and the chances of missed connections at Thorpe I wonder do any of the Bittern Line services form a Lowestoft service and vice verca like they used to ? If not sadly the bus might be a safer bid.

Just because it uses Linux does not mean the interface for managing it is any good. It could be, if someone takes the effort to understand how it is used and what the interface requires (called Usability design or UX for short) but that is not always done well.

User Interfaces are like jokes, they shouldn't need to be explained.

A very valid point!

I wonder if any operational staff have (ever) been consulted with on PIS design and specification?

Of course they haven't. After its installed we get no manual. Just muddle through with information shared in the mess room.

Why bother asking the very people who are best placed to help improve things? :rolleyes:

I heard today that 2 156’s have been hired back from EMT to help cover with the lone 170.

Do the people ordering trains say they will talk to the operators so the developers don't need to?

That happens way way too often, especially in larger corporations, the engineers design the system and often the interfaces as well, taking no heed of usability. The current project I am working on shows it does not need to be like that.
