Eugene Bostwick retired 15 years ago, but now he’s taken on a new job as a train conductor. More specifically, as a train conductor for rescue dogs.

He never intended to spend his retirement caring for abandoned dogs, but when dogs started showing up on the Fort Worth, Texas, property he shares with his brother, Bostwick had a choice to make.

"We live down on a dead-end street, where me and my brother have a horse barn," he told The Dodo. “People sometimes come by and dump dogs out here, leaving them to starve.”

Bostwick and his brother Corky took the dogs in, fed them and took them to a vet to be spayed and neutered.

“We made a place for them to live,” he told NBCDFW.

Although the dogs have plenty of room to roam on his 13-acre property, when Bostwick saw a man pulling carts of rocks with his tractor, it gave him an idea. Thus the “dog train” was born.

“I started out with my tractor. I had a little trailer and I put four or five dogs in there and took them riding. Then more dogs started to show up and I said, ‘Uh-oh! That’s not enough room!’”

To create more seats in the dog train, Bostwick cut holes in eight plastic barrels, attached wheels to them and tied them together. Each “train car” is the perfect size for one of his numerous dogs.

Now Bostwick is a dog-train engineer who — much to the delight of local golfers — takes his pooches on twice-weekly rides through the Sycamore Golf Course behind his property. The ride takes about an hour and a half.

Bostwick’s brother told NBCFDW that caring for the dogs and taking them on train rides is a tradition that will definitely continue for the 30 years he has left.

"I’m only 86,” he said. “My wife said if I didn’t get up and do this I’d be dead, and I really would."
