How does this engine always get mistaken with a different identity? We're solving the mystery to untangle the train name confusion. The SECR P class is one of my favourite steam engines of all time, so here's an explanation of the preserved locos of the class.
To clarify, this video was made long before Jago Hazard's recent video touring the Bluebell Railway fleet. Many Thomas fans have had the same confusion of seeing No.178 and thinking it's Primrose due to its fame in The Railway Series.
This wasn't really directed as a full Guide Rail, but skims over the histories of each of the 4 surviving P class tanks. I may come back and do individual factfiles on them.
