Wilwi, simple answer to your enquiry is that you cannot transfer a route or anything else between Trainz Android and any PC version of Trainz. Google Android is a mobile operating system for phone and tablets, while the PC version(s) are run under the windows operating system which is strictly for Laptops and as stated PCs. The forgoing would be the case for all applications and not just Trainz.
You also do not have your Trainz 12 version registered which will make it difficult to get any (if not all) content downloaded into it.
