Description
RailPrints seeks to provide players with a set of basic building blocks for building two track or more rail that can be composed and used to more quickly create rail networks. These pieces are provided with varying curves, inclines and medians to give you choices and flexibility.
This set is Right Hand Drive by default. Stations are not part of this set and likely will not be. However, if you have a station set with a similar philosophy to RailPrints that also lines up well, I would love to link it here! Drop a comment or message me on the COI Discord.
Currently this set contains no electrified track pieces (introduced with Update 4).
Note that I am not super familiar with the track markings (No-stop, exclusive); some of these may need work on that end. Please do mention if you come across one that deadlocks or could be marked more efficiently!

12 April 2026 - R9 Progress Update
Hi, it's been a while! RailPrints took a bit of a hiatus while I burned out on CoI and had other things to deal with but with CoI Update 4 it is back under development and now has a horrifying amount of new stuff to make thanks to electrified rail. In the interim I've significantly scaled back the ambitions of R9 (and all the web stuff with R10 is completely out). R9 will now focus on achieving several things:
- Fill out the Intercardinal (IC) set as much as possible, bringing it up to parity with the Cardinal (C) set
- Fill out the Angle Transfer C-IC set as much as possible, to make interfacing between the two orientations easier
- Remove 2 Median and 6 Median blueprints to make space in each set (these removed pieces will be re-released as an RP Extra later), leaving 0, 4, and 8 as the median sizes throughout RailPrints
In addition, there are a few things that were planned but will no longer be made, mostly to do with 22° blueprints. There are some unique challenges with creating track blueprints at that orientation, as well as the overall low usefulness of the set, that have led to this decision. Angle Transfers will eventually have interfacing with 22° angles but there will not be a full set of pieces similar to the C or IC sets for that orientation.
As alluded to earlier, electrified track also presents a huge problem for RailPrints. I would like to do a RailPrints Elec version that is simply all the existing stuff but electrified; however, this is a massive undertaking that doubles the number of blueprints in the set, and complicates maintenance later on. The current solution of place non-elec blueprint and electrify it will have to suffice for now.
I had also anticipated splitting the existing RailPrints packs into smaller chunks so they could be more complete while complying with the hub limitations on blueprint sizes; with the removal of 2 and 6 Median pieces, this plan may not be necessary and will be evaluated later. R9 will continue the same general structure as R8.
R9 is currently set for some time in April/May 2026. Thanks for your patience everyone <3

Special shoutout to the many Factorio blueprint books of similar philosophy that provided the inspiration for RailPrints!
