If you want to work with OpenLayers, you can simply create GPX files 
from the routes you want to draw (there are GPX export functions in JOSM 
and Merkaartor). Then you'll need a list of stops and their positions. 
To couple stops together, you could search stops that share the same 
name and find the intersection of the line connecting the two poles with 
the track you are drawing. Finally you need to draw the labels. 
OpenLayers should support that, but I haven't used this feature yet. 
Hope this helps.

cheers
