@Forester1,
If you're still looking for the 'Coal Unloading Facility' from Matruck, I found another way, but it is complicated:
1. Go to www.wayback.com
2. Enter www.checkrail.com in the search field
3. Scroll to the year 2016 in the middle of the screen.
4. In the calendar below, move to one of the blue circles.
5. Click on the time shown.
6 At the top of the screen, you will see a field ending in 'checkrail.com:80/
7. Add the following in the field 'routes/ek3/ek3_mick.cdp', and hit enter.
8. Download the cdp, which contains the file you want.
