I would love to see an F40 on San Bernardino and Antelope Valley but as backdated. I think the F40 has to have its own timetable considering it is retired. This train would suit the route in its own timetable as it is an icon for Metrolink over the years and it will add more gameplay to the routes.
Metrolink only ever owned 1 F40, so it would be kind of pointless to make a backdated timetable for 1 unit......
we are getting F59PHR soon, which even though is modern, kinda looks more like those older locos and am sure will be cool to drive
