What could have happened like nearly happened to me as a "Child"
Crossed a manual crossing soon as a train went passed,
which actually blocked out the sound of a train coming
in the other direction, and because i was being clever
to cross as soon as the first trains arse passed i didn't
even see the second one.
Luckily i was young enough to make it across the other side,
and the back draft almost pull me back into the track.
Point i'm making is one train can block the sound out from another one
i then went and changed my shorts
