As along time computer geek - hence [com]PUTER NUT - I have just invested in TS2019 after much confusion with TSW - the 'W' is a whole different world. My train simmimg goes back to MSTS X and before and I find the 61-bit running so smooth compared to 10+ years ago. Antway enough garbage dom me. Just be warned as a bona fide pensioner I askmany many questions <GRIN> and answer a few if I can.
Welcome to the forums puternut glad to have you, always feel free to ask as many questions after all that is what the forums are here for.
