Sorry if this is already in one of the threads but I thought they were being put on TSW 2. I got East Coastway but not these two.
look at the roadmap here https://live.dovetailgames.com/live/train-sim-world/articles/article/tsw2-roadmap-18-august
Everything from TSW APART FROM NEC AND ASSOCIATED STOCK will eventually be in TSW2 it will be released over the coming months, so NTP and LIRR will be coming sometime in the near future.
Apparently the roadmap is quite out of date from the 18/8 and some items should be releasing shortly, what those items are can be found in the UPCOMING section of the Roadmap. Note that not all of the items in the UPCOMING will be released at the same time. The update coming next week should provide some clarity with items moving from UPCOMING to NEXT ARRIVAL.
