DB has stood its class 90's down and Freightliner use their few erratically and then you got a class 92 each way over night so its hardly an intensively worked electric freight service anymore. That said i agree its a nonsense we still have the original oil circuit breakers in use here and even if the enhancement has been stopped they should be replaced under normal renewal budgets. Theres plenty of redundant VCBs off ECML that could have been transferred in the interim if they've been holding off waiting for the final HS2 gameplan to be developed.

Considering that when the line was electrified between Crewe and Liverpool in 1961 all passenger and freight trains changed to electric power. And in those days there were a lot of freight workings into the Merseyside area. So where has all the power gone?

I presume modern trains are heavier with more safety features, tilt hardware on 390s, more current pull for air conditioning, automatic doors etc..Trains go faster at 200 km/h and faster accelerations use more power. There may be fewer freights but they're probably bigger.

There never seems to be more than 2 electric trains on that line at once, surely it has enough power

Does it not also depend on where the power supply to that line also feeds, and over what area? Doesn’t necessarily cover just that line.

Under normal feeding it ought to be sufficient but NR will want to cover at least an N-1 condition (loss of one of the grid infeeds for example at Crewe) to maintain normal service an adjacent infeed) which could would effective double the area being fed and thus the number of trains so there is a risk of overloading the remaining feeder and it tripping on overcurrent.
It is surprising that ECML is the recipient of a vast power upgrade and that North end of WCML which carries far more traffic is left in some places on the 1960's kit and at best the early 1970s distribution equipment. The problem with electrification is that its often not really obvious on train running that the system is running with an outage but at some point probability will conspire that a double outage occurs in the same area and then no electric trains will be moving.

Although it must be said that the ECML does see a good number of Passenger trains and little electric freight trains. In some areas dual mode trains are running on diesel for now. Till upgrades are completed

On the WCML the OHL to Manchester and Liverpool was installed in the Mid 60s and is now approaching 60 years old. From Weaver to Glasgow that now is approaching 50 years old. Although North of Preston trains are flighted together and could be spread out to allow more use of other electric trains.

I was under the impression that Crewe-Manchester (at least as far as Cheadle Hulme) was comprehensively upgraded during WCRM (new OHL, bi-di signalling etc), around 2002.
The same was true of the North Staffs line which had two rounds of upgrades, the SRA being dissatisfied with the first effort.
There was also work on Crewe-Weaver Jn (eg new fast line at Hartford Jn), and towards Liverpool, but maybe not to the OHL other than making it 125mph.

Could have sworn I saw one of these wizzing through Bushey on the down fast about 13:20 today. Could it have been or just a cut down 5 car Pendolino?

Reminds me of the plan for Virgin to acquire some "minilinos". How many cars were they going to be ?
Click to expand...
The introduction of 22 6-car Baby Pendolinos to replace the WCML Voyager fleet was part of the Virgin franchise proposal in 2012. Sir Richard Branson was photographed shaking on the deal with Alstom's CEO.
A lot of preparatory work was completed, including trials of multiple unit operation with pantographs raised on each unit. The new trains were to be equipped with autocouplers to allow push-pull operation to Chester and Holyhead using Class 67 or Class 68 locomotives.
Sadly it was not to be, following the collapse of the franchise award. The new fleet would have been in service for more than 8 years now. Definitely a sliding doors movement for Alstom in the UK.

Presumably using wires all the way from Darlington.
But has to reverse at Wolverhampton as it cannot use the unwired direct link from Bushbury Jn to Stafford Rd Jn next to Oxley.

It’s not on delivery, it’s heading back across to continue more testing. Unit is still not accepted by Avanti, and is still a Hitachi test train.
