Railroad Ink: Engineer Expansion Pack

In the multiplayer puzzle game Railroad Ink™, your goal is to connect as many exits on your board as possible.
Each round, a set of dice are rolled in the middle of the table, determining which kind of road and railway routes are available to all players.

Use the 4 special dice of the Engineer Expansion Pack in addition to your regular Route dice, and find new ways to score points:

Construction (1 die): perform special actions and restructure your networks!
Renovation (1 die): modify pre-existing routes and add more connections to them!
Separation (1 die): increase the challenge of your games with tricky expansion and its never-connecting routes!
Special (1 die): build Special Routes in a whole new way and score a lot of points!

Note: at least one core set of Railroad Ink™ or Railroad Ink Challenge™ is required to use this expansion pack.
