Old Idea: Untitled dimension game

I think I was in fifth grade when I thought of this concept. I remember it because I was going to a new school and I felt the need to doodle about alternate dimensions. The concept was that there was this large train that traveled through different worlds. More like different times and spaces such as advanced time. For example: the player could uncover a locked gate and travel using a special wand to a dimension where the lock was rusted away. I don't recall why there was a train in the game, back then I just went with my first instinct. There was a pair of siblings who guided the player. The girl didn't have a name but the brother, if I remember correctly, was named Brock. I sketched all these different types of wands the player would use to affect the world around them. I never got very far with the concept and quickly moved on to other ideas. It turns out I may have been ahead of the curve. About a decade later a game called Quantum Conundrum came out with similar ideas. Instead of using wands the player would use a device that altered the landscape to make object bigger, smaller, lighter or heavier. It was designed by a former Portal dev who wanted to maker her own concept. Of course, my game would be too complicated since I had all these different wands.
