There are fast line platforms at Queen's Park but nothing is booked to use
them, nor has there been for some years. Silverlink County services have
used them in emergencies and IIRC some late night trains have stopped there
on occasions, usually when engineering work has been taking place.

Are you sure? I thought there were DC line platforms (used) and WCML
slow line platforms (used only in emergencies and being discussed in
the context of this thread), but no WCML fast line platforms.
