Stuck in Red Faction 2

[CrowDog]

Im at a train bridge and Im supossed to blow up three pillars I guess. There are 2 items by my friend but I cant pick them up. I dont see anything in my inventory that would allow me to blow anything up.

You have to crack the pillars (throw down a grenade by the pillar & you'll see the red bomb exposed) then attach the bomb inside.
