The Black Belt Caterpillar Wrestler is led to one of the doors at the back. It has a new notice on it "Hobby rooms". Underneath in smaller lettering it says "Removal of the above notice can lead to temporal and spacial discontinuity".

Inside is a second door with a notice saying "Be aware that entrance to the hobby rooms can be a source of temporal flow rate anomalies. Please do not leave before you enter."

Through the second door is a long corridor with labelled doors. He passes many including "Driftwood collection as art", "Fire walking", "Lithographic repairs", "Oxford comma deletion society, and eventually finds "Railway and railroad modelling, including tramways".

He opens the door and a few lights come on showing a small area in a vast two storey space. He is on an upper floor overlooking row upon row of model railways. Stairways descend between layouts and into the central areas of those that are circular. A sign indicates a stairway to one side and behind him is "Workshops, machine shops, paint shops, casting, etching and 3D printing." The way forward towards the array of layouts is signed "Replica model layout collection, if you cannot find what you seek please ask by speaking aloud using the preface 'I know I've put it somewhere'".

As he moves forward more lights come on, showing layouts that he remembers from his youth and since, The Madder Valley, The Sherwood Section, Lagoona and Silver Waters, Pendon Dartmoor and Vale and many more.

The door behind him closes. Will anyone tamper with the notice outside?
