Ferroequinology: Running Boards

We hoisted engineer's side running boards onto the brackets mounted the previous week. Now, it is possible to access the top of A&WP 290's boiler shell. We used the opportunity to heat and remove a handful of brackets to clear several sand and steam pipes.

Protip: when applying a socket wrench to a red-hot steel nut, make sure your gloves are dry to prevent any unwanted heat transfer...

Update: water soaked into gloves acts as a thermal conductor resulting in scalds if a gloved hand is applied to steel whose temperature is several hundred degrees above the boiling point of water.
