I think it was discussed but cannot find it :

A routing unit will not pass trough a friendly unit except is SK INF or ART .

1) What happens if behind the passed trough unit there is no space for the routed unit ?

2) as the routing unit is stopped by the first friendly unit encountered, do all the units that should have been passed trough test as if passed trough ?

Think you have it mixed up, steady can't move through routers, but routers will burst through friends if they can't shift to avoid.

I found it :
Pg 71 and it concern only routing unit moving during ther own move turn

routers move fir if the movement phase.st, you cannot move through a unit that has moved.
