I like the direction, but Action on Exit should be split into different toggles so every player can really make shuttle do exactly what they imagine.

The options could be:
- remove depot (first entry) from schedule
- remove other stops from schedule aka return to depot
- toggle manual mode

For example when I build new outposts I want the shuttle to wait for me there, but not loose the depot entry.
Yes I abuse Shuttles as FARL and outpost builders.

Just to clarify my understanding of your preferred options :

1. The problem with this option as I see it is that if you don't have any other entries in the schedule and you don't set manual mode it will just spam the "train has no path to 1" message which would be annoying and is the reason why i made the Hibernate option work like it currently does
2. Return to depot is already an On Exit option so that's not a problem
3. I totally agree that just setting manual mode whilst not affecting the schedule should be an available option and this will be added next release for sure

I'm not sure why you feel the depot entry needs to stay in the schedule though ? You can just jump in it and use the hotkey which just adds the depot to the schedule and takes you there anyways

I personally have my shuttle in hibernate mode and just use the new Send to Depot hotkey if I want to send it away, which is practically never because if I go somewhere I don't want to be stranded there and have to recall it. I also have a seperate FARL/Builder train simply because otherwise i would have to make every PAS stop 3 carriages long then which would make my layouts more bloated.

The problem i have atm is that I want the shuttle train to be a small, fast, non invasive means of transporting yourself around which is why I'm working on bringing back the double-headed single locomotive shuttle, but I also like the fact that people can use it as an easily controllable FARL/Outpost Builder if they wish to. It seems like everyone likes to use their shuttles in different ways and trying to coalesce all the different usages and maintain its simplicity of use is actually proving to be the hardest part of the whole endeavour for me so far.

Hopefully i will have time later today to add the manual mode On Exit option and make the depot name changable in the settings, combined with the Depot hotkey i think that would give people a bit more flexibility in usage until i can decide on a more permanent solution.

Why did I ask those things? I didn't know there was a go to depot key.

I didn't even think to look in the FAQ since very few mods actually use it and the portal shows the FAQ tab regardless.
Maybe write "Manual in FAQ" or something in the Information tab.

Allowing custom name(s) for shuttle depots would be nice. I like to start all player stops with # so they are sorted to the top.

I started with pure L-L player shuttles. Then I wanted to have a material to build a new mining outpost with me. Then I didn't want to go back to depot, swap to FARL drive back out to lay down new tracks. And so I ended up with a L-4C-L FARL-Shuttle.
PS: I'm using nuclear locomotives and heavy cargo wagons from Train Overhaul. So my FARL is the equivalent of vanilla 3L-6C-3L.

Thats probably a good idea, I did also update the forum thread with the new information but working on the documentation is definitely on the ToDo list for this week because your not the first person who has contacted me about something because I haven't done a good enough job of making the information available to users :) It also doesn't help that i broke the changelog last version and didn't notice until this morning which had it been working probably would have helped alert people to the new stuff.

I usually drive out to a new location in my shuttle using a temporary stop, then just use Fat Controller to call my FARL to me once I've set up the start of its run, my FARL/Shuttle are MK3 Bob's stuff with engine overdrives so they are pretty speedy and i don't think I've ever done a run in it that's used more than a few thousand rails in one go so one cargo wagon has been sufficient for me so far.

As far as personal transport goes I have all my passenger stops prefixed with PAS, with PAS as my GUI filter and my home stop is called PAS AAHome just so that it auto sorts to the top of the list, I'm considering adding another new hotkey, probably CTRL-ALT-J for a 2nd programmable stop but I'm not sure if thats necessary at this point. I also want to change the standard call function so that if you have a GUI filter set it will call to only shuttle with that filter rather than just the nearest available so it doesn't pull into a LTN controlled goods station and cause a delivery to timeout which happened to me a few times recently.

Maybe i will do a quick video or something explaining the mod's features and ways to use it, as usual you have given me lots to think about :D

It would be nice if you could document what the hibernate mode exactly does -- currently, I cannot find a description anywhere. (Including old Forums and Mod Discussions, because I did not realize it was a new feature of the 0.17 continuation)

That information is now provided in the FAQ on the portal and forum, thought I had done that already but clearly not, thanks for pointing it out :)

Trains behave weird when using temporary waypoints alongside the return to depot action.
- make trains open the normal train ui instead of folks list
- enter a train in auto mode at a supply stop
- select any temporary stop for it

The train will wait the 5s from the temp stop at the depot instead of going to the temporary stop first.

Yeah I see what you mean, for some reason it seems to think its arrived at the temporary stop without actually moving, as far as i can determine its not related to the OnExit mode as it occurs no matter what mode you have set, as far as I'm aware nothing in the shuttle train code should cause it to do this, I'll investigate it further and see if i can work out why this is happening :(

The other mode i tested it with was hibernate.
Doing the same with a train in manual mode works as expected.

Ok, this actually occurs the same way without Shuttle Train mod loaded, which leads me to believe its nothing to do with my mod at all and is some problem with the game itself because if my mod isn't installed it pretty much cant be causing this ;-)

Just for clarification though, OnExit stuff only actually does anything when the driving_state_changed event is triggered and your no longer in a vehicle so it should be irrelevant to anything like this anyways.

I guess I never tried doing this with non shuttles.
Should I make a bug report or do you?

Well you found the bug so I'll let you have the honor of reporting it, Replicating without my mod was the first thing I tried as I was fairly sure nothing in my code would cause this. Temporary stations seem a bit buggy and ill thought out atm anyways.
