Lyric discussion by atthedrive-in 

weeell buttofmalmsey i dont know Bono personally but the lyrics seem to suggest a drug addiction - "i took the poison from the poison stream, then i floated out of here."... and... "she will suffer the needle chill." the lyrics in general seem to articulate some sort of hopelessness - some kind of desire to escape from something that you know you really cant (addiction) - hence the term 'running to stand still'.

also, "step on a steam train" cooould be a reference to what people call taking heroin, 'riding the H-train'. or that could be looking too far into it.

anyway i think this song communicates hopelessness and dependence beautifully.

"I took the poison from the poison stream" Could also be the singer's adulterous meanderings, allowing him to float out of a bad relationship and be held in some loving arms too.
