I stumbled upon these on YouTube and I can say that these are the best Trainz tutorial videos I have ever seen. They are extremely well made and can take a newbie from knowing nothing to being a very knowledgeable TRS19 user in just a couple of hours. The user Sharadise announced the channel here but it seems to have gone unnoticed by many users. In addition Sharadise archives twitch sessions on the channel too. These show in great detail how to build a beautiful and realistic layout set in Pennsylvania.
