That picture you showed earlier certainly answered a few questions in my mind about the railway. I can remember the park railway as small child after its line had been shortened and always wondered exactly where and how it ran through today's MB. I can see from that pic now how it ran between the the buildings from the site of the Teacups out to today's Haunted Hollow which always confused me. Now the the slightly odd way the MB bay toilets are built makes perfect sense. Thanks for this @Squiggs and keep this coming!
Seeing that pic also shows how much of MB is modern extensions.
