too bad that this portal doesn't allow subscriptions to mods and/or threads like this. thus i often don't see answers in time ... anyway, i finished getting most achievements (only the three speedruns are missing), and thus am starting modded games again, and thus also finding this mod again :-)
Been super busy, finally got around to fixing this up for versions beyond 14.2, please enjoy the updated version and report any other bugs!
yes, here are two replies to this, using 0.14.20 now:
1. starting a new game with this mod is working now. thanks
2. when i wanted to research this junkrail tech, the icons are bad or even missing completely: the icon for the tech itself only shows the topleft quadrant of the icon, and at "effects", i see 4 squares of which two are empty without icons: first is a rail icon with text "2x curved scrap rails" (did you really re-implement curved rails and how do i build a straight track), second ("junk train") has no icon, third ("train stop") looks ok, and the fourth ("portable chest") is an empty square without icon again.
Since resources in the base area are very scarce on my map, this mod comes very handy to transport resources to my base at a very early stage (barely started red science) ... researching the tech now while writing this text :-)
edit: I have used the train now, and it looks really nice and works well, besides the missing icons. those icons are not only missing when selecting the tech, but also in the craft window and when i have the engine and the wagon in my inventory: only a grey square can be seen, in the inventory and (if i have enough resources to make one) also in the craft window with some number on it, but completely invisible in the craft window if i don't have enough resources.
imho, the engine and the wagons also need some adjustment of their sprite offsets: the engine looks as if it doesn't drive on rails but 2 or 3 pixels too far to the south (seen when the train drives from east to west). and the attachment part of the first wagon looks a bit strange too, as if it would be on top of the engine but not attached to its rear.
but all this are minor adjustments and overall i love the looks of the junk train !
one last strange effect : when i mouseover the engine and wagons, i am shown a yellow rectangle of length 3 for the engine and length 5 for the wagons. thus i would assume that inserters can load the train only in that range (and for a handicapped junk train, such a limit would be ok, maybe even a limit to 2 for the engine's coal and 4 for loading wagons, since 4 also would match the coverage by small power poles while the "normal" trains' 6 accessible tiles match the coverage of medium poles). but when hovering over the signal or trying to place an inserter, the usual white frame is shown with the usual length of 7 tiles, and (also as usual) 6 of those 7 tiles are usable for loading. only for UNloading, it is restricted to 5 usable tiles, just as i had expected for loading AND unloading. and the location of those 5 or 6 tiles doesn't match the white frame well: white frame from tile 2 to 7 of the wagon, and yellow frame from tile 2 to 6, unloading matches the yellow frame at tile 2 to 6, but loading matches neither frame ("loading 1 to 6" instead of "yellow loading 2 to 6" or "white loading 2 to 7"). did you accidentally subtract 1 from the front of the wagon instead of from the rear end when looking for positions of inserters ?
sorry for the long text, but since i couldn't post (here in the portal) a picture of what i mean, i had to describe it in detail ...
