No — tracks can only be moved onto empty spaces; you cannot leapfrog or share a space with another track (p.9).

You may split a track-extension action freely between your routes (p.8–9), but at scoring you only count spaces that your locomotives can reach; each track scores for its space and any empty spaces behind it treated as that track's color (p.20).

You must take the lowest-numbered locomotive available and add it to one of your three routes (Trans‑Siberian may hold 2, St. Petersburg and Kyiv at most 1 each), and you may only add a locomotive to an empty slot or by upgrading a lower-numbered one (p.10–11).

When you take the two temporary workers you cannot use them to resolve the action you just took, but you may use them during that same round as if they were your own workers; you must return them to the action space at the end of the round and cannot keep them for the next round (p.15).

You score the points shown on the industry track space your wrench is on; if that space shows no points (for example a factory), you score the points printed on the previous space instead (p.21).
