I am all set up. May wind you up by texting or posting a selfie while grilling a steak and drinking a G + T or indeed a beer. Oh I forgot, it is dry January

No it’s not, it’s to be treated as Live at all times but is only actually Live when testing takes place

Here's useful quote I found from a month ago which answered a question I was going to ask (what is the main purpose of tonight's test?):
Also, to quote myself from a couple of pages back, here are the links for the individual timings:

Still shown in RTT today as terminating at Preston on those dates with bus forward to Manchester Airport.

- (5Z90 2230 Allerton Depot to Preston) Does not appear to have started according to Realtime Trains at 23:15
- Am I reading this correctly?
I believe so. However 1N87 appears to be booked for a Class 319 and is due in Preston at about the same time.

This service was cancelled throughout due to a delay not investigated (OU).
Ah well... Off to bed.

GPS worked!
Gralastair spotted that 5Z90 had made it to Wigan, albeit 17 down, he texted me and off I set. Three miles down the road he rang me to abort the mission, so I'm back home in the warm and dry with a flask of soup for supper. Immense pain saved as a hundred miles round trip in the early hours in the snow for a no show would have been, er, miffing.
Thank you Gralastair.
Good night all.

Also there seem to be a lot of T3s on Traksy, along with this (which may be a works train that would be blocking the test run). At least it appears to be down to external factors.

Could have been worse Dave; considering the way the weather turned with snow and black ice evident this morning. Let's hope tonight 's 5Z92 appears from 5Z90 and there will be something to video.
Wonder if there will be a further run inserted next week or tonight's run will be enough now.
There's a T3 possession booked tonight through Bolton from about 2230 til 0550 tomorrow, won't be any test trains via Bolton.
Tomorrow night there is also a possession (different possession limits and timings) but the PLPR train (flying banana) is meant to be about too in its protected path, running as 1Q44.
Soup can be a bit earlier tonight!

Thanks for the info. Probably at least one week before a new path is created to carry out the runs.

I saw the BUS - all the way through Bolton - what is a T3 possession please?
5Z90 is still showing in RTT as running from Allerton Depot to Preston though.

Possession for engineering works, with max 25mph through the entire work site/possession zone.
The speed limit is lower for going over points and entering sidings (there may be a few other exceptions).
Obviously not going to be doing any 100mph testing with the possession on.
After standard GE/RT8000/T3 "Possession of a running line for engineering work"

Is EMU testing going to resume since the past 2 nights have been cancelled due to this T3 thingy or is that it til the may TT change?

It just absolutely has to - the question is - when.

Presumably, it'll all need testing again by a 390 once the extension lead is connected up and energised (and up to 100MPH as well). Which, I would have thought would be before the May timetable change as drivers will need to practice up to that speed. After all, we don't want trains flying through stations where they're supposed to stop!

wonder if they're finishing off the extension cord over easter then they can start testing.

Tony Miles has a piece in Feb Modern Railways after talking to NR about lessons learned from the project.
He describes the gap between initial testing and general authorisation being about safety-related changes to convert temporary solutions into permanent ones, together with general "snagging".

Drivers won't need 'practice', they will be well acquainted with the route and can adjust for the higher permissible speeds. Some services are already being run using 158s cleared for 90mph via Bolton and Chorley.

But the line has a 75MPH limit on it at the moment according to posts up-thread so I would have thought that many more drivers will need familiarisation with the 'new' units on a 'new' route. After all, 319s don't handle like 158s - or do they?
Drivers are used to doing 100mph on 319s or other traction on other routes, and they also know the route via Chorley. No more familiarisation is necessary. 319s are absolutely pitiful above 80mph anyway, they won't get to 100mph via Chorley. The 331s should fare better.
Incidentally 158s have very similar braking characteristics to 319s.
The permissible speed has been increased on plenty of routes in the area recently with no problems, drivers' route knowledge is dynamic enough to adjust for higher approach speeds. Station overruns are a rare issue, indeed there have been several I am aware of via Chorley in recent years, but they are far more likely to be down to complacency/lapses in concentration than anything else, if infrastructure has changed then drivers will adapt and have heightened awareness the first few trips over a route. Significant changes see drivers given classroom briefings before they see the infrastructure in the flesh, a simple increase in line speed doesn't usually warrant a brief.

probably use the 323s and 331s on the bolton line and leave the 319s for the liverpool lines.

That's been clarified it's just a blanket 75mph limit for electric trains (which aren't yet authorised) . As mentioned, 158s (on their own) can run at 90mph, and for what it's worth 185s can run at 80mph. All other DMUs are 75mph max anyway .
