Milton neutral section is just on the Ely side of Cambridge North. There where ongoing issues with power supply between here & Littleport since GN started extending fast Cambridge terminators to Ely. Not saying this is the reason, just a guess.

Still not enough power at all times for Class 755s, mainly peak times but it would be an difficult message for drivers to say which trains can run in electric and which ones should stay in diesel. Are they actually allowed to operate in electric mode in passenger service yet anyway?

If you were inclined to guess a little further, do "supply issues" = voltage drop? I've been told, (by the electrification installation team at a Colchester open day) that when the Stowmarket feeder was offline the voltage in the area dropped to 16.5 kV, which wasn't such a problem back then. Today's electronically controlled rolling stock may not be so tolerant as 86's, etc.

There is still a problem when Stowmarket is offline. Class 360s were banned north of Ipswich Yard the last time it failed (last year sometime).

Yes they can operate in electric mode. For the time being however drivers are advised to remain in diesel. It's all still very new & confidence is still building for those that have been passed out on them. Looks like ASDO issues are almost rectified too so expect Brundall Gardens & Haddiscoe calls to be reinstated soon.

What about 745s for Norwich, I know one went down to Liverpool St recently, but is the power supply from Stow-Norwich enough for a 12 car IC train or will the feeder need to be upgraded?

Had a lovely ride from Cambridge to Norwich and back on two 755s yesterday. I don't really have anything to add from what has already been said, but IMHO they are without doubt the best new train we have seen for a long time.

One observation though - there seems to be a weird checkered film covering all the windows. I have attached a photo which shows this. It's not that intrusive when looking out of the window, but does anyone know why it is done?

From what I've heard about other recent Stadler trains, it is a metallic film intended to reduce the amount of sunlight getting in while still letting a phone signal through (which a uniform film would block).

Interesting. Glad to see it's a calculated design choice as I would expect on an otherwise brilliant train. Can't say I like it though, especially on a train with Wifi.

Come again? The window film is designed to allow mobile signal through. What does it have to do with WiFi?

Well, if you have WiFi you don't really need to have a mobile signal, as all of its functions (internet, SMS and phone calls) can be substituted with internet over WiFi or are mostly obsolete anyway.
Some phones don't support calls over Wi-Fi, and I find on many trains the Wi-Fi is not working or the speed is awful, so using my phone as a hotspot is a useful backup!

Yes, so why is this window film that still allows phone reception a bad decision that someone might not like? I don’t understand the logic.

I never use the on board WiFi. It's always slow and unreliable, better off just using my 4g connection on my phone and tethering my laptop to that.

It makes it difficult to see out of the window. Like contravision on a bus.

I'm not sure what is difficult to understand.

I can understand English perfectly well thank you.

You wrote “Can’t say I like it, especially on a train with WiFi”. Tell me exactly what that has to do with seeing out of the window please. Nowhere in your post had you mentioned looking out of the window, am I supposed to be a mind reader?

The idea of it is to reduce sunlight, the normal windows allowed phone signal to go through anyway. @ivzem is saying that it reduces sunlight and let's data pass through. So this new design doesn't matter about the WiFi or phone signal, it matters how much sunlight is shining through.

I would assume that a post relating to film stuck on a window relates to looking out of a window, especially since I have posted a picture showing the somewhat restricted view.

If the train had no wifi it would make more sense to allow a better phone signal, but (as ivzem has explained) on the Flirts I don't feel it's necessary.

The mesh doesn't allow better phone signal, it ensures less sunlight passes through, AND phone signal still works inside the train.
Hopefully that's clear enough.

Surely there must be a better way than checkered film? Blinds, curtains or even a uniform translucent film (at the expense of phone signal) would be preferable for me. Like with contravision, my eyes doesn't know whether to focus on the view behind or the grid pattern.

Latest timescale from Greater Anglia is they expect all the bimodes to be rolled out by February/March 2020 which is said to be in line with previous guidelines.

170s still scheduled to start leaving in a couple of months as planned originally, looks like they may not be getting extended. Any news on derogations?

No 745s for a little while yet. Monday's to Friday's you'll normally catch a 755 on the Cambridge diagram starting with the 06:33 & on what was NC37 short set diagram on the Wherry Lines.

Is the Cambridge diagram Cambridge to Norwich or Cambridge to Ipswich?

Any timescales on when they’re likely to appear on the East Suffolk?
Will concentrate on the Wherry & Breckland lines for now. They need to be easily accessible to/from Crown Point & within range of the ROG cl37 Thunderbird. The East Suffolk with its single lines would cause havoc if a failure occurred. Units on there interwork with other routes out of Ipswich making diagramming difficult.
