Acceptable Graffiti

I took this on my last time through Truro rail station, I have probably walked past it dozens of times without noticing but it caught my eye.
It seems to be a brief history of the railways systems progress over the years from its inception until the arrival of the Intercity system.

After an early telephone call it was a morning at the rugby club to provide access and information to the Chubb Security engineer carrying out his annual inspection and certification.
This is the start of an easier week than last hopefully.
