Demon Train Map ?

Hey all , I really want to get my party back to Faerun in their own time from the 40 years in the future - I was hoping to have a demon train do it, in true Halloween style. I cannot however , for love nor money find a suitable VTT Map that I can use or amend into place. Has anyone seen a demon train map anywhere online?  I have an idea that each carriage moves them back in time, and they need to "beat" the train driver to end up in their own time and not hell or something similar, but I am fluid if I can find a map for visualisation !  Can anyone help 

Tom Cartos has a set of maps for a train station: &nbsp; <a href="https://mab.to/FtZUAjHURTPsu" rel="nofollow">https://mab.to/FtZUAjHURTPsu</a> &nbsp;that includes train cars. Look for "Grand Western Station" under ""Dorran City Complete".
