The First Blitzkrieg - Rail line repair units

[ajtateson]

I'm pretty sure only RailRoad engineers can repair the rail lines. Construction Engineers cannot.
As VM says above they benefit defense but I'm sure I read somewhere in the manual that they are also useful when attacking enemy fortifications. I think if you attack an enemy fortified hex with a force including a Construction Engineer unit it reduces the effective level of the fortification by 1 (for that attack only - I don't think they actually destroy the fortifications).

I should say that what I've said above is just off the top of my head so I apologise if anything is inaccurate.
