This would be a very small event placed around Ian, the station's lovable corgi.
SCP 2952 is just that, a corgi that is over 30,000 kilometers in length, quickly regenerates all damage done to it and functions as a transportation similar to an underground train that transports very small welsh people that vary around 3cm in height via holes located in different locations on the sides of the corgi.
Attempts to seal off entrances into the corgi will cause the welsh commuters to become enraged, causing potential harm or hinderance to the ones responsible for sealing off the corgi in the first place.
