Thanks guys that is wonderful.
As in all things the options to do what you want is sort of buried in Qgis and
once you know that its there you wind up kicking your for not spotting it
before.
As you say Style,, click on the lowest level of your line and the details for
the line appear including Offset option, I had just been looking at the the top
options.

Subject: Re: [Qgis-user] drawing transport networks sharing lines
You could try adjusting the X and/or Y offset for each tube line
although it doesn’t draw them exactly parallel. In my example my line width is
2 units and I have duplicated the lines and offset one layer 1 unit and the
other -1 unit

Well, depending on how many classes you have for routes, you could make
each type (class ) a differnt width, and stack the lines on top of each other
with the widest one at the bottom of the stack.
If you don’t have vertical order control, you m,ight be able to get
away with some level of opacity applied to each trail in order to see through
to the next line type.

I am trying to draw a transport network within qgis, sometimes two
network links share same path with the result the qigs draw each link on top of
each other.
Is there anyway of getting qgis to draw the links next to each other?
For example with the tub network the district and circle line is drawn as two
lines yellow and green next to each other when they share a common route. Qgis
would draw the green line on top of the yellow line
