I Created a multiplayer session - but can't play it?

So I created a basic multiplayer session to try with my friend who was new to Trainz (I've played Trainz for years off and on, but not much multiplayer).

Turns out that I can't even drive my own session in TRS2019 - even tho I used all basic pre-loaded content - because it isn't official content?

I was thinking gee. I could convert the route and session to a cdp file and upload it to my friend and we could play and test the route out as I develop it. But is this not something that is possible?

MP is run off of the N3v servers, not your computer, so no you can not.
