Is there any way to implement a specific train route where a train goes to a station to provide items and at the same time brings back a different type of item to the original station for recycling?
Example of what I'm trying to do: red/green catalysts in Angel & Bobs, where you send catalysts to a process and at the same time pick up the used carriers to be recycled.
I would want to implement is a a single train service (i.e. one single provider station and multiple destinations requesting/providing the carriers to reuse) with 1 wagon for each of the catalysts types and 1 empty wagon to bring back the used metal frames. Would it be possible to maybe manage to do this with LTN somehow? Would there a better way of handling this, perhaps that I'm not thinking atm?
My previous A&B base was done purely on the vanilla train system and with just that it was easy to implement, with just some circuit magic... but since this time I started this new base with the purpose to give LTN a serious try I would want to try my hand at doing this with LTN if it's at all possible.
There are several processes that require multiple types of catalysts at the same time and then also need to get rid of the used frames back to reuse them, so having a single station on each process managing that saves a lot of space and train traffic... hence why I'd like to do it like this, but I'm open to suggestions/ideas too!
Best regards.
