Hi jenny
In answer to your question about the under ground tunnels to the station yes there was across hill street
I do not know how old you are or whether or not did you ever frequent that top part of the hill in years gone bye
But they was still being used right up until about 1961,2 period for the transporting of delivery up to the post office and sorting offices
They used to drive up through the tunnels up the under ground hill to to get to the post office for collecting of any mails and par cells by the sack load
They would come up to the post office under ground and then appear out of them to cross over the rd of hill street and up besides the crown pub
Which was there route when walking up hill street you had to be careful for these little trucks coming out
There used to be signs on the wall as you walk up hill street as you would pass there opening where these little trucks would. One out to cross over the red
There was also a big car park within the building of these tunnels for loading the post office vans which also used to come out
So you had to be very weary of crossing this opening it was later years they changed the name of the pub which became a very busy pub at night
Sadley I cannot tell you when the crown was first open end even thou it had a plaque above it many years ago on the side of the building
So as you walked up hilll street looking up the hill as you walk you would see the name and date I can recall the new name and roughly the date of that changed
Name and date as I seen the renovation best wishes astonian,,,,,,
