This could be great for a park-and-ride concept. Going to subscribe to this and explore this concept for the city I'm building.

I don't know. I'm not sure how the game handles this issue...I assume it is done automatically, but I've been wrong before. The only thing I can tell you is to test it out and see if it works. If not, just unsubscribe. Good luck and have fun.

I mean the garage...

not sure. I think you can use it normally either way. it depends on how you drag the line through the station from what I understand.

Can player use this normally in LHT games?

they actually do. also, if you want to have a very busy garage, have a good amount of residential around it.

Will people use it like a park and ride (commuters)?
