this route came out in TS Classic in 2019. I hope it gets put into the August Roadmap. Anyways here are the trains included in this route. Class 450 and Class 444 in Southwestern Railway Livery stopping at Woking , Guildford , Poole , Fratton , Havent , Portsmouth & Southsea , and Portsmouth Harbour. The route also features Class 166 AI between Portsmouth & Southsea , Portsmouth Harbour and Guildford. And Class 377 AI between Portsmouth & Southsea and Portsmouth Harbour
For this route you'd need a 455 atleast for all the metro services around London - If its just desiros the route would be way to unrealistic and horrendous to play due to lack of metro AI+services around London. Also "between Porstsmouth Harbour and Guildford" The North Down Lines run through guildford that is true but your wording makes it sound like it will run the entire way up the PDL untill guildford. Maybe its just the horrendous one paragraph format. And while we're at it can we just backdate it like 5 months so we can have 313 services at Portsmouth, cheers. Good route to be added but bad format + missing a lot of information + missing a load of vital additions. My thoughts anyway.
Agree, that it needs a 455 as does the BML. Aside from wanting an AC London route first, I would love to see Waterloo to Portsmouth in TSW3. Add a slamdoor layer on later.
