Ever wondered just how much work goes into keeping things running on our heritage railways?
Earlier this week, Ffestiniog & Welsh Highland Railways posted some statistics on just how far their engines had travelled during 2015.
In total the combined distance was over 63,000 miles, enough to travel more than twice around the world.
Garratt 138 led the pack with over 14,000 miles travelled. While Merddin Emrys was top of the Ffestiniog engines with over 8,500 miles in the year.
