Question by J: I know NOTHING about electric trains. Link provided for following questions….?
I want to buy this electric train set for my daughters room and have it mounted up high out of reach.
First: What does “minimum curve size O-27” mean? Does it mean how tight a curve the train can make?
Second: How can/should I go about mounting the track to the wall? I’ve seen this in someone’s house but I don’t know the person to even ask.

“O” is the track gauge (size) while “27” is the diameter of a circle made using the track, meaning it will have a 27″ diameter. O-27 is also compatible (for the most part) with normal O scale track, although some O scale trains may have trouble going around corners because corners using O-27 are several inches smaller in diameter than normal O scale.

If you want to mount it to the walls, I would just make some simple wood supports you can mount to the wall then attach the track to. Make sure you attach the track to the supports under the track joints, and also midway through each piece of curved track. Also, ensure the supports are wide enough to allow both pieces of track to lie on them. For the supports, I would make them so that if you viewed them from the front they would resemble a “T”. The leg of the T is a triangle while the top is a square. You screw the leg of the T to the wall and the top of the T supports the joints/curves and allows you to attach the track to them. You can also make it look nice and add a french curve to the front of the T’s leg.

If you want to spend more time/money you can make a complete roadbed for the track using planks of wood and mount it to the wall using the T legs I mentioned earlier. This would be the preferred option. Here’s a picture of what I’m talking about (with different supports though):
