The Underground

Found a cave under a hill, and looked inside.
It was an Aladdin's cave of old tinplate railways. An endless underground station, rusty and neglected from the 1950's. Somehow all connected to my father. In fact, it may have been an aspect of him, somehow.
The cave was only around half a metre high, but I was able to walk around in it, explore.
The tracks seemed to go on forever, as did the cobwebs.
I started to walk further in and the way back seemed to get less clear.
Perhaps to go on was a strictly one way affair.
I returned to what I thought was the 'Way Out'
