If you are starting with the hobby again, my advice is that before you see how you are "rusty" with your skills. If the result you get is to your liking / promising, later it attacks the metal tracks (without forgetting those of plastic link-to-link, of great variety/qualities/diffculty).
I hope I have helped you with the matter, and sorry for the "brick of text" ... lol"
Francis: Thank you so much for your comprehensive reply. Wise words which I will follow. My daughters are buying me a Christmas gift of a Tiger in 1/35th scale, with a reference book. This will be fun!
Kind regards
Gary
