Hi there! I see the http://www.brainbombers.com website is now showing a welcome gallery of pictures of the new game, very nice design!
The download link is for the old version of the windows game, however at the bottom there is a link to the apple store for an ios 11.0 version version of the new game called Model Railway Easily, 440MB size.
Does RTR become MRE?!
(Unfortunately I own an ipad 4 ios 10, unless you can make it compatible for it…)
