Steam
How many times can you upgrade your locomotive in one turn?
The rulebook limits the Move Goods upgrade to once per turn, and posters read the tile as a separate upgrade.

Once in Move Goods. Each turn you may improve your locomotive only once in that phase, and the upgrade uses one of your two activities, so you cannot also ship a cube with it. The Locomotive action tile is separate, so a player who takes it can also upgrade in Move Goods. An upgrade always raises the level by one, never several at once.
