Also, is any connection into a city valid, ie can I use a cross track and turn at right angles into a city or do I need to use a curve?
No you cannot. It is impossible for trains to turn straight angles. You only have two types of track available: a straight and a soft curve.
Finally can I use a two-track tile and leave one track open at the end of the 3 rounds (I think I can but just wanted to check)?
No, you cannot place a two-track tile on a vacant hex. You can only place ONE LINK (of up to 4 tiles) which MUST be one single continuous line. Two-track tiles can only be used to upgrade a hex with existing track when you want cross that existing track. So one track of the tile is already in the hex and you just add the second track.
PS - How do recommend marking track ownership, I'm thinking a train on the start and finish tiles would be best, especially around the crowded NE?
You can do whatever you prefer. The convention used by publisher, designers and most players is to place a single locomotive on each link. Most often placed on the central hex of the link, but that depends on the layout.
