I was at Swanage Railway Station yesterday and saw 34028 Eddystone. I noticed on the cabside, just above the number, it had "7P 5FA". Now, I know what the 7P and 5F refer to, but what does the A mean?
On the sublect of Steam Locomotive Power Classification, how do they work out what the P figure should be for a loco type - same question really for the F figure, and for MT?
Also, on the cabside, there was a yellow circle. I assume this was for Route Availability. Is there a published list that states what each Route Availability actually means when they are working them out? Otherwise, how do they work out what the Route Availability figure is for a particular line?
