When it comes to your son’s love of trains, you’re a doubting Thomas.

Here are five less-commercial ways to encourage working on the railroad.

First Stop: Collect handcrafted lumber cars and tankers. Made in Portland and built to last, the wooden vehicles are beautifully constructed mostly from mill scraps ($28-$160).

Second Stop: An old-fashioned engineer’s cap never goes out of style ($11).

Third Stop: Little conductors wear their hearts on their chests in a cartoon character-free cotton tee ($30).

Fourth Stop: Cover your tracks with a bold modern canvas depicting movement. Part of Avalisa’s Things That Go series, the hand-stretched print comes in three sizes ($60-$160) and looks so cute hanging in his room.

Fifth Stop: Keep on chugging to the roaring melody of “Choo, Choo, Choo.” It’s Hullabaloo’s spin on the little engine that could ($12).

All aboard.
