I certainly agree, but it was perhaps easier for the Simrail development team since they came later. They simply did the opposite of what DTG was doing. DTG built standalone isolated stretches, in Simrail it's a network, TSW is single player only, whereas you have multiplayer in Simrail, TSW scope is the whole world, in Simrail it's just Poland, etc. I think the problem with TSW is that DTG tried to please everyone... I seem to recall seeing Belarusian routes for Trainz, and I'm sure there are also railfans in eastern Poland. So far, the Simrail team hasn't tried to cater to them. But perhaps one day it will be possible to run a Warsaw - Minsk night train while by that time Swindon may still not be in TSW...
The other caveat with doing a Simrail style approach in TSW would be having to provide an increasingly huge timetable. SimRail gets round that by only having a full, somewhat fictionalised as it repeats every hour regardless of time of day, timetable for MP. Single Player relies TSC/MSTS style on a handful of playable scenarios, albeit with the ability to sub in a different train if you wish.
