Railroad Ink: Engineer Expansion Pack

Usually, yes: roll the relevant Expansion die or dice with the four Route dice at the start of each round. The Special and Separation dice are exceptions—they replace a basic white Route die of your choice (p. 1; Separation die, p. 2).

You may use it only once per round, on a space that already contains a Route and where the Route fits completely within the die’s dotted lines. You can renovate only basic Routes, not Expansion die results; the two dotted-square faces can only add connections to an existing Station (p. 1).

Yes, using the Special die is mandatory, just like using any Route die. You can still use the Special Routes printed at the top of your board (p. 1).

You may use its effect at any time during the round, but only once per round. Destroy erases a drawn space; Move erases and redraws one in another legal location; Free Placement lets you draw one of the current round’s Routes without connecting it to an existing Route (p. 2).

No. You cannot apply its effects to Expansion dice results, except results from other Engineer Expansion dice (p. 2).
