I'm having trouble building the Martian Express, where I can't build any trains. I've finished building a railway line, two stations, and supplied them with power and goods. But I can't build any trains. I started a game in creative. I've researched all train-related technologies, even built a drone hub. But I still can't build any trains.

Any suggestions?

Hello,

It's a little complicated.
First, you have to build the stations and the tracks, which you already have. Then you have to build one or more trains in the stations. You can choose whether you want to transport freight or liquid goods.
You then have to select the train in the station and place it on the tracks.
You may also need to adjust the storage quantities or whether freight should be sent out or just balanced.
Hope it helps.
