New signals at Essen

Even with the new HSL4 to the Netherlands opening in April 2007 , signals on the old line 12 from and to the Netherlands are currently being replaced with new ones.Maybe this has something to do with the level crossing ahead : now the signals are exactly at the railroadcrossing , but the new ones are located some 100m before it so they can let a train stop at the signal without the need to close the level crossing.
