Hello, A few days ago I discovered an old train set that my dad had bought for me when I was about 6 years old. After some research I discovered that its an HO scale model. I have plenty of tracks here but the connectors to tie those tracks together are missing. Can anybody help me with what they are called and where I can buy them? I've attached a picture of it here. The ones circled in red is what I'm talking about.
