Dear OP - there is no such thing a a 2 Amp 14 volt battery - that is the minimum DC requirement to run a large scale train on TRACK power since you seem determined to do that in spite of the awful conditions you are trying to run in.
Dunnyrail above has given you good advice, as have many of us here over the last hundred and a half posts. Your MAIN problem is trying to run at ground level in what appears to be the middle of a construction site, with track lying on the ground at the risk of constantly getting trampled on or covered with some kind of crud.
Until you can get your track at least a foot off the ground all round you are wasting your time and effort.
I really can't offer any more advice, except for you to call up John in Guelph - Winona Garden Railways - and tell him that you've spoken to us at great length with no tangible results, and ask for HIS much-nearer advice. HE might even come over and see your location - he's a good guy,
