As Merseytravel are a Rail North partner there is perhaps the option of issuing an ITT with 3 lots for trains for 3 different franchises (Merseyrail, Northern and TPE), allowing the possibility for a manufacturer to quote a reduced price for all 3 instead of pricing and awarding each lot individually, unless that breaches tendering rules.
Rail North isn't a TOC or ROSCO, so I doubt it would order trains.
The nearest equivalent is DfT with Class 700/800, but even these were only proxy orders for the TOCs.
They were also service provision contracts, not direct procurement.
Even then the class 800 financial deals for GW and EC were different.
The requirements for ME, NT and TP are wildly different, so it would be a tough call to come up with a spec for a single train type for delivery in three tranches.
Eg a 110/125mph-capable long-distance EMU for TP is no use to Merseyrail.
There is also the fact that Siemens is entrenched at Ardwick. Changing supplier would be costly for TP.
My guess is that TP will get to buy what it wants, while NT and ME will be much more constrained by cost.
(I think this might be better in another thread...)
