Hi all! I mis-posted this in a different thread, JUST noticed this Beginner's Q&A forum, sorry! Below is my question, minus the pictures (upload folder is full lol). Pretty sure this will be a quick one and done trip to the train store in town, but confirming.

Hi all! Another newbie here; getting back into the model train scene after, oh, about 40 years. My dad and I had a Lionel set in the attic back in the late 70s. Those were good times. My father in law has passed his along to me and frankly I'm behind the times - my kids, 11 and almost 13, are expressing an interest and I don't want this opportunity to pass us by. I'm not sure what scale I have or what kind of track. I'm having trouble attaching pictures due to their size; thanks Samsung! What can or should I look at on the train itself or the track to help ID this stuff?

I need to know what kind of track this is, and what I need to get the transformer to work on it. There is a hobby shop in town, so I should be able to pick up whatever I need today. I'd like to have it up and running under the tree tonight.

Thanks in advance!

Edit: Just from asking around at work, looks like all I might need is a specific piece of track fro those leads from the transformer to plug into. Can anyone confirm/deny before I look silly walking into the local hobby shop?
