George VI's funeral train travelled from Paddington to Windsor. No overhead cables then, and less need for security measures.
But Queen Victoria Royal funeral train was delayed in 1901 on the
GWR▸ .
The delay did lead to the tradition of Royal Navy pulling the gun carriage, on 2 February 1901 the weather was extremely cold and the hawsers for the gun carriage to be used for the procession from Windsor railway station to the Castle had frozen. The horses intended to pull the gun carriage were also affected by the intense cold and had become restive and possibly dangerous during the wait for the delayed funeral train to arrive.
