Potentially, then there's the possibility to drive different ones. I've always found it interesting how in Thomas & Friends, the engines are their own characters. In earlier books it's more vague how much control the driver and fireman have, and to what extent they're wrestling with the personality of the engine. In later books and TV series, the drivers may as well not even be there, it's practically the engines themselves driving around and talking to each other.
This is much better than my train game! I came across a bug where selecting the same tool more than once at the station would cause increasingly large explosions. Also it's not always clear what's collecting what, or how to reach some of the coins at odd angles.
It looks very pretty! It's a shame you didn't get to implement the gameplay, but from your description it sounds like you're getting more efficient at game development so in future you may be able to achieve more in the same timeframe :)
My eventual goal is to add RPG elements, such as characters to speak to at stations, quests to deliver goods, and unlockable exploration of a railway network.
The short-term goal was to implement the difficult bits first (track-following, wagon collision) so that me and my son can work on the interesting bits together!
I like this one! To begin with, I thought the speed of the flute-playing matched the speed at which I was moving the vikings, but it was just a coincidence!
