Not seen any posts on this but the route extension, JT signal / level crossing enhancements and upgrade to the 165 look pretty impressive. https://www.justtrains.net/in-development/wessex-main-line-southampton-salisbury-extension
Day one buy for me. Jt did a fantastic job with the mml series and I know the developer behind this route extension so will be fantastic.
I agree I have every single extension for the MML to make the huge network the quality is just fantastic
The Hope Valley extension has a number of errors - the worse being Slade Lane Jn between Manchester and Stockport where a Double Slip was used instead of a Diamond Crossing - it does not sound like much but if you had spent 28 years going over the junction as Train Crew it stands out like a sore thumb. I will reserve judgement on the old 165/166 unit until I see some pictures.
I am really looking forward to this, I really like playing this route anyway so the extension will be brilliant I am sure. Did not realise they was going to update the 165 as well which is even better. Everything Just Trains has done recently has been brilliant.
