i quess you have nodes already done, so here some info, in entity category (category with 3 blocks visible) in the decent vahicle tab you got traffic light and station, just spawn station, put it near road, and change it name to anything but not blank, then you can enter taxi, then select that station. Or using that station you can call taxi what will come to you to pick you up

ah, i see, thanks

I tried naming it but i cant type anything and theres nothing to choose from.

I have same trouble, then I check pressing C and Rclick on the "taxi station" then I could change the name. you need 2 taxi station with diferent name and there you go. just place the taxi station close to waynodes thats all.
