The question is whether Merseyrail have ordered enough units to be able to do much meaningful pairing up.
And the answer pretty much is no!

They will no doubt pair them up for the Grand National and other major events in Liverpool.And the answer pretty much is no!
There's going to be 52 class 777s in total, there's currently a total of 59 class 507/8s.
Would any account be taken of a reduction in reliability over the years? They should (might/hopefully/fingers crossed) be very reliable now but in 10 to 20 years time? If more trains need maintenance what happens then? Just a hypothetical question really...The argument is I believe that they will be both quicker (and so take a couple of minutes off each run) and more reliable. But we've heard that before.

They can't order more trains now because reliability may decline in several decades time, though it really shouldn't. A mid-life overhaul should address any age related issues that crop up.
Yes, but the mid-life overhaul itself takes a unit out of service for some time, potentially leading to shortages, and extra demands on the rest of the stock. You can't plan for the future expecting 'best case scenario' every day from entering service to final withdrawal without risking being "bitten on the bum" a few times!
The 777s will have MUCH better acceleration so should save more than a couple of minutes on the longer routes. This might free up a couple of units compared to 507/508 and with any luck higher reliability will mean fewer in maintenance each day. It does look tight but I am looking forward to sampling the acceleration of the 777s.The argument is I believe that they will be both quicker (and so take a couple of minutes off each run) and more reliable.

Has anyone seen sightings of 507033 on the Merseyrail network recently?
What does this type of overhaul involve and the average time the overhaul takes?C3+ Overhaul at the moment.

I heard that they have stopped C4 overhauls of the current fleet, what other types of overhauls would take place in the final few months/year of the 507/508s?
