Well each will have to clock up a certain number of miles of fault free running. Then there will be driver training

I am guessing it will be a fairly similar regime to that of the Avanti 805s and 807s, however I am guessing a lot of EMR drivers will need training on OLE.
Maybe a few but not many. Most of us already drive 360's . All of the London and Kettering drivers do and quite a few Derby. Just some Derby drivers that might not , but it's part of the normal rules anyway.
A lot more testing is required with the 810s, due to the different carriage length, new engines etc.
A 810 is about 70% a different train compared to all other 8Xx variants.

If it is not silly question, if they are doing tests on diesel, why do it on a busy electrified line, not the unelectrified section.
Similiarly if testing platforms and clearances, surely would want to do it it in mode train will normally be working in the area, not in alternative power for non electrified areas

Why is diesel mode classed as degraded version? These units are able to achieve and keep to time operating at 125mph, so doesn’t matter which mode it operates in.

I imagine it's all part of testing. You'd need to check platforms and other interfere issues in both modes.
Not sure if the Pan-Down signs for 810s are in place yet. (Until the knitting on the MML is upgraded)

Is the linespeed still higher in Diesel? (I seem to recall this was the case?)
The tenor of this thread suggests that might no longer be a concern when the first 810s actually enter passenger service!
Yes, but we're talking about whether it should be using the OHLE on the test runs that were scheduled for today.
It can’t use the OHL for the test runs, as it is not authorised for use in electric mode anywhere on the midland mainline.
As the carriage lengths are different to previous, it is currently undergoing pantograph testing on the ECML, so all tests, when they do start on Midland mainline (now tonight Old Dalby to Luton), will be in diesel mode for the time being.
Unknown when electric operation will be allowed on the Midland.

Signs in place, but covered over.

Sorry if its been asked before, but why do they have to perfectly match the performance of the 222s, surely the couple of minutes lost on the diesel section can be made up on electric, much like with the avanti 805s.
To maintain the pathing on the congested southern section of the midland mainline where they share with Thameslink?

Surely they would be on electric at that point though
The wires between Bedford and London are only rated for 100 mph.
When the wires are able to be used at 125mph yes.
But as they are not ready, the intention was to operate in diesel to maintain 125.
However as the wires may actually be upgraded and ready prior to passenger introduction, at that time then they will be able to operate on electric at 125mph.

Is there a thread on the 125mph OLE upgrade?
A quick search on the Infrastructure section of the forum brings up the below thread, I presume that includes about the upgrade of the southern section.

That thread includes discussion of the upgrades to the OLE south of Bedford, interspersed with discussion of the extension of the OLE north of Kettering. There's no separate thread. You may have to look through a lot of pages to find relevant posts.A quick search on the Infrastructure section of the forum brings up the below thread, I presume that includes about the upgrade of the southern section.

Furthermore the work south of Bedford is part of two different programmes - not all of it is for 125 mph.
If you search for "OLE125" or "OLE 125" you'll find many of the more recent posts (primarily within the afore-linked thread) on that topic.

I thought the eventual plan, once electric running along the MML is authorised, was to run pan up between Cricklewood and STP because the line speed isn’t above 100mph and so as to eliminate diesel under the wires when standing at STP?
More of an interim stage, but yes. Supercoss has previously mentioned plans to install APCO balises (and/or pan up/down boards) just NW of Cricklewood station, whilst [Scratch or Boreham]wood has also been suggested as such a location by industry press.

Certainly Bedford to Kentish Town on diesel anyway, until all the OHLE is upgraded.
Class 810 specific signage has been installed that requires pantographs to be lowered ( on the move) going North around the ‘Apex Corner’ area, where the M1 motorway runs parallel ( between Mill Hill Broadway & Elstree Tunnel) but this signage is still sheeted over , the actual location where line speed increases above 100 mph is back at Cricklewood so a 4 1/2 Mile ‘void’ exists where obtainable line speed ‘pan up’ exceeds the current 100 mph limit on pantograph raised obtainable speed.
I’d guess this location has been chosen as a “ straight bit” of track and catenary.
The only way round the issue is to acknowledge signage is in wrong place Or Instruct drivers to obey “ EMU 100” permanent speed restriction signage until they get to pan down location
Are 810s to be treated as an EMU or HST with regards to speed signage ?
in summary , read from top to bottom attached graphic

Noticed an 810 parked in Doncaster Carr IEP depot today. Anyone know what it was doing there?
