Not true. With the advent of calling signals over the radio, when
multiple trains were heading up the road, it was easy to figure out.
Here is another example. When switching the southend of Glasgow, the
control signal needed to be passed numerous times. So, we would tell the
dispatcher that we needed to work by the signal and he dispatcher would
put the signal on "fleet" and we had a favorable signal each time we
needed to pass it.
