Based on "a small enthusiast website" planned movements for Tuesday, 3rd March 2020, there are approximately 1200 trains in this scenario over 24 hours.

Freight services have been set with appearance probability so no two runs will be exactly the same in that regard. Note also that 2M/2O Southern, 2C/2D Overground, and 2T LNW services will appear late if their predecessor services were delayed out of Euston (but some rules are omitted to enable service recovery).

Known Issues
===========
Services reversing at WM1184 need to be talked through - notes added.
Run-round service 0O07 needs to be talked through reds - notes added.
CS Loco 0S25 needs talking through from Up Sidings - notes added.
Trains between Camden Junction and Acton Wells Junction (crossing at WWLJ) don't step up their timetables.
Trains from Willesden Euroterminal Down don't step up past No. 7 Jn. [Unconfirmed]

Some LNW and Voyager services at Euston have been slightly changed from the diagrams to match the information from RTT.

Some freight types have been guessed at, based on the available information in WTT (Books CY16, LD06, PF01 and WK01).

Other Notes
==========
Southern (2O) services from Watford to Clapham have a generous timing allowance on the UWR line. Hold them to time at Mitre Bridge if necessary to avoid delaying Overground (2Y) Stratford-Clapham services timed ahead at VC818. CHECK YOUR SIMPLIFIER!
Euston Platform 16 is in the WTT / RTT, however platforms 16-18 are currently OOU due to HS2 works. It is just about possible to accomodate all the services with extensive shuffling.
