I loved that Video Toots.
Ray I think they remake and replace a lot of the critical parts. Ive seen a spitfire being restored, by the time they were finished 70% of it would have been new metal.
On a lot of the metal parts, they do become distorted from heat. The boiler and firebox, though, normally operate at temperatures higher than the common house fire, so in most cases, simply cleaning it up is all that is needed.Same with locos that have been burned in roundhouse fires, etc. Doesn't the heat damage the metal?
Those "before and after" shots are amazing. I've always wondered how it is that a loco which has rusted and rotted for so long, can still be restored? Same with locos that have been burned in roundhouse fires, etc. Doesn't the heat damage the metal?
