I would like to see the Dutch railways. The NS (Nederlandse Spoorwegen) has beautiful models to ride with, the Hondenkop, the Koploper and for example the Intercity.
TS1 seemed to miss routes and stock for the Netherlands. As a result the Dutch community seems to have been very resourceful in producing freeware and also payware like the excellent Chris trains DLCs With TSW it’ll be interesting whether DTG again ignore the Netherlands - and leave the community to their own devices - or whether they’ll consider some Dutch content. Personally I’d like it and would think that some route like Amsterdam-Rotterdam would be well enough known to gather wider interest.
