Simulation Train Simulator DSME Production Preview

Hi All
As a person born a year before the transistor was first successfully demonstrated in 1947 the last 22 years have been a steep learning curve in computers which has resulted in my first attempt to create a computer train simulator.
Now retired, my profession was in illustration, cartooning, 3D modelling and animation, engineering, industrial design and prototype creation. I did not want to waste this experience so I decided to create a Train Simulator project for the model engineering society I am a member of. I started this project in November 2019 and I see no end to it as this sort of project simply evolves over time. I may never live to 'finish' it! This is the first preview and the second preview is nearly complete. Check it out if you have the time and any comments, hopefully constructive, will be appreciated.
