Not going to vote because I don't have TSW and I'm not likely to get it any time soon but yes- I think she'd be an excellent choice for TSWs first kettle not least because she's readily available in the flesh so to speak and is completely modelled in CAD by the A1 Steam Trust. I'd suggest she be offered with all liveries though rather than piecemeal as she is in TS for which you can get her in Apple Green as a stand alone, BR Green in the Settle-Carlisle Specials pack and BR Express Blue and Grey primer "running in" livery as separate add-ons. I rather like the Express Blue but will it work with the S&C Specials model which is the only one I have? What a mess. (Shouldn't this be in the TSW pages BTW?)
We already have Tornado in TS 2018. There is the Peppercorn A1 DLC in apple green, the BR Express Passenger Blue and Ex works grey liveries on the market place and the BR Brunswick Green in the Settle Carlisle Specials pack.
