are they're any worry of the 745s getting flat tyres from sitting in a sidding awaiting commissioning?
How long does it take to check the tyre pressure and pump them up? <G>are they're any worry of the 745s getting flat tyres from sitting in a sidding awaiting commissioning?
Absolutely not. There are potential issues with leaving a train parked for an extended time powered down outside, but "flat tyres" is not one.are they're any worry of the 745s getting flat tyres from sitting in a sidding awaiting commissioning?
Not sure if that's a troll post you were responding to, but that's not how you get wheelflatsAbsolutely not. There are potential issues with leaving a train parked for an extended time powered down outside, but "flat tyres" is not one.
I think it was just a wind up. There are however issues with wheelsets when stabled for very long periods from what I am told.Not sure if that's a troll post you were responding to, but that's not how you get wheelflats
They are stored on the additional running line not on the running line so they will not be moved. The MNR has been operational throughout with constant movements for DRS.Another light engine movement from Crown Point to the MNR this morning.

It may be that whatever it is just needs to be moved rather than entering service. I understand that GA units were being stored along the MNR running line due to a lack of space. This year’s running season begins on Sunday so they will need to be out of the way.
So why would it be done ?Pathed as means very little, it does not reflect the type of stock actually used.
Because the new fleet isn't fully introduced yet - it's to denote what performance can be expected of the train in the timetable. It's not appropriate to change the timing for services for new stock until it's very likely the new stock will actually operate that service, otherwise if a new, faster unit doesn't work it, it will become late every time it runs.So why would it be done ?

You might well not see the RTT header changing until a timetable review related to stock or some such - think December maybe - you might / or might not see the whole new train fleet start over the next few weeks (or may timetable)So we won't be seeing many anytime soon given other comments in this thread
There are two units in use at the moment, and weekdays at least they aren't too hard to find. If you're waiting for a particular service to become 745-operated that isn't already, though, you could be in for a fair wait. Given current lack of progress I wouldn't expect the whole 745/0 fleet to be in service until May at the earliest, longer still for Stansted Express.So we won't be seeing many anytime soon given other comments in this thread
If I understand correctly then, the timetable is agreed and becomes public for a certain time frame but parts of it are liable to change after a review - at least if you have a plan you can change itYou might well not see the RTT header changing until a timetable review related to stock or some such - think December maybe - you might / or might not see the whole new train fleet start over the next few weeks (or may timetable)

And for the next joke posted , we awaitare they're any worry of the 745s getting flat tyres from sitting in a sidding awaiting commissioning?
Never heard of that happening. What does happen is damage to axle bearings (brinelling?) if vehicles are stood in the same position for a period of time. Storage sites will often move vehicles (and are contracted to do so) to prevent this.wasn't intended as a troll post, i know train wheels can get a flat edge after sitting stationary for long periods of time, my uncle who used to work for Connex at Slade Green towards the end of there ownership of the SE franchise and he talked about one of the networkers (465 014) developing flat on its wheels after sitting unused in the depot being used as a source of spare parts for the rest of the fleet
according to him 465 014 was sat at the very back of the depot and had all its traction motors removed, making the unit effectively a dead unitNever heard of that happening.

Mark 3s sat at Long Marston don't have any traction motors, either, but they still get moved.according to him 465 014 was sat at the very back of the depot and had all its traction motors removed, making the unit effectively a dead unit

I was told - quite reliably - that at least two units were ready to be accepted - all fault free running completed - but suffered wheel flats and currently needing attention - I.E wheel turning!Not sure if that's a troll post you were responding to, but that's not how you get wheelflats

something to do with them having suffered the wheel flats while being shunted around - possibly a parking brake left on??
I simply cannot believe that! The wheels would have been worn up to the axle - surely. The sparks from wheel rubbing rail as it was dragged along would surely have been flagged up very quickly - you would hope! Maybe a few kilometres, but no chance along the whole journey!i do remember hearing about one of the stadlers (may of been a 755) that had its brakes on all the way from europe

are we talking an axle/bogie set? or are you suggesting the whole unit had it's brakes jammed on?had its brakes on all the way from europe
I can believe that this could happen, but I'd have thought years, rather than a few months. Not like corrosion's going to get in, so it can only be the weight of the unit pressing down on the metal. One would have thought it'd be strong enough to withstand that for a very long time indeed.wasn't intended as a troll post, i know train wheels can get a flat edge after sitting stationary for long periods of time, my uncle who used to work for Connex at Slade Green towards the end of there ownership of the SE franchise and he talked about one of the networkers (465 014) developing flat on its wheels after sitting unused in the depot being used as a source of spare parts for the rest of the fleet
I remember seeing a photo of a vehicle of a eurostar that encountered a seized wheel of some kind - about a third of the entire wheel was missing. If a Stadler had a wheel locked going all that distance, either the brakes would have caught fire or it would have suffered a similar fate, so I'm sceptical about that having happened. Brakes on by mistake when doing depot shunting seems far more plausible, if extremely embarrassing.i do remember hearing about one of the stadlers (may of been a 755) that had its brakes on all the way from europe
They are towed completely dead and I understand they have to be specifically set up to be towed, don’t forget the parking brakes default to on when no air is present. Units standing around due suffer bearing damage as the weight is concentrated in just one spot it’s good practice to move the unit a few feet every month or so.

Brinelling is usually only a problem where there is vibration present. Bearings on a wheelset out in the countryside are unlikely to end up brinelled.Where I work the engineers manually rotate the stored electric motors. Many of these are large, as big/bigger than traction motors, but obviously have less weight on their bearings than a railway vehicle.
