The rolling stock: Class 321: This train is a EMU Built Between 1988 and 1991. Currently 32 of these trains are in operation. This train has a max speed of 100mph and has an acceleration of 0.55 m/s.

This line also has an "All Stopping" service calling at: London Liverpool Street, Stratford, Chelmsford, Colchester, Manningtree, Ipswich, Stowmarket, Diss and Norwich. Overall: I believe this route would be super fun as it combines express with scenery and historic towns which would make it stand out compared to a lot of other TSW2 British routes which are mostly built up (IOW obviously an exception as the whole thing is countryside or historic places)
With the class 321 you will need more stations. You have missed out many stations. Below is all the GA stations:
Likely too big a project to produce in one go sadly. Maybe as far as Colchester but not all the way to Norwich. (There's also all the metro stations between Liverpool Street and Shenfield to model as well, which would be a large task in itself).
I sure do love the Mainline with 9 stations. Express services may only call at nine - but the rest still exist and would need to be modelled.
Id prefer a Cl90 era version of this route simply because the Class 90 is one of my favourite looking locos and with a rake of Mk3 and a DVT. Or we could go really retro and have a class 86 in raspberry ripple IC livery.
Excellent idea you can probably get away by ending this at Ipswich or Colchester with Branch Line. Some London Liverpool Street services are Class 755s or rare cases of Class 755. There can be a Rhein-Ruhr Osten like scenario to where you must use an emergency pantograph button to continue. For Class 755 pantograph failure means finish the journey on diesel power.
