Rules Is Rules

First of all I hope everyone is safe from this dreadful weather . . . windy enough here but much wors in other spots. Stay safe.
Attended my first stretch class this morning . . . no pressure and excellent . . . thanks Steph. Now I am over 240cm . . . with more to come.
Quick food shopping then ruined the flexibility by crawling under that model railway again to try again to fix the electrics.
Gave up and decided to do some revision from the book shown  . . . the Fat Controller insists I know all the rules before being allowed to open the railway. 
Final Traitors tonight . . . hope you all have a grand and safe weekend ahead !
