I think that as we already have the Portsmouth Direct Line (PDL (Waterloo - Portsmouth)), it would be a great idea to create the branch that splits from the PDL at Woking and heads off to Weymouth. Yes we already have the Southampton-Bournemouth section of the SWML but I don't think that it is enough track. Maybe later in the future, they could be combined into one DLC but for now I think it's best to have them separate.
The 2d map on the original PDL Woking-Portsmouth route has bare bones track and landscape. Routes radiate from Woking and Guildford towards Southampton, Reading and Redhill. I understand that the original PDL was used as a base for the Waterloo-Portsmouth route so there might be further extensions in the future.
I would love to see Weymouth in Train Simulator. Also I would like to see an extension from Southampton to London via Basingstoke
Free steam era Southampton-Weymouth here, unfortunately no extension to Weymouth Quay though. https://steamsoundssupreme.com/page_fwrp01.html
Would love to see this expansion, especially the completion of the triangle around St Denys - Fareham - Eastleigh expanding on and linking the Southampton - Bournemouth route (currently ends at St Denys) and the Portsmouth Direct Route (currently ends at Cosham). Having this would result in a fairly complete SWML route set and includes the historic railway town of Eastleigh, which has the Eastleigh works and Railfreight depot for great scenarios. It would also be a component for the suggested Portsmouth Hrbr to Salisbury and westwards route. I'd pay more to complete this network.
