On this topic a bit more Clifton Hill is a slightly odd station in that it 
allows for trains to use either of the platforms in any direction,a feature 
that is normally only seen at stations where trains regularily terminate 
but I dont know of any trains that did other than the odd parcels van.
Another similar station on this line was Alphington , which allowed for 
terminating trains in the down platform and then crossing to the up line to 
run back into town .Never say a train terminate here either. 

May have something to do with the time when Alphington to Ivanhoe was single 
track, a bit before my time .
