I was discussing the holding area at Sandhills with a mate who's a driver on Merseyrail and mentioned people's concerns ...
He said they have the same in use at Aintree for the National meeting etc and he's adamant that it works great. He also said they've been test running 8 carriage trains and we can expect them to be approx every 7 to 10 mins on match days.

But like everything we'll just have to wait and see.
