You might need the gel type of superglue - sometimes called gap filling - depending on how tight the rail is when you slide it back on.

My best suggestion would be to contact a local train shop and ask about model railroad clubs in your area - there are groups almost everywhere and most are ready to welcome new people without question.

Dues should be fairly reasonable and members will be happy to show you all the mistakes they made along the way learning bout the hobby.

Not much involved in this hobby is really hard, just lots and lots of details, easy to mess things up.  Don't worry about the scale of the group you locate, much of what we do is transportable across scales.

The spookshow blogs are great - start at the beginning with layout one, you will get a good history of one man's progress and some of the mistakes he learned.

Don't know where you live, if you give me a city and state I can try to find a group near you.

Good luck!!

I am not much on DCC programming - managed to get mine converted to the cab number but let me say WOW.....and once again WOW!!!

Slow speed creep is amazing - pulling 40+ coal cars on the club layout (ok so it is flat) at a crawl with no motor growls or whining......

Again Wow - great job on a great looking model.
