The first five photos from a week or two ago detail various stages of installation of the copper sheets on the front end of the car's roof:
And the last two photos, taken more recently, show the front end of the car's roof following completion of the copper sheeting installation with all of the joints sealed up. Very impressive work!
Car 73 is a big car and there's a lot of work left to do, but the compound curves on the ends of the roof are obviously the most intricate and complicated parts of the roof work. This is a fairly unique accomplishment; I can't think of any other cars in traction preservation that have had this kind of copper sheathing totally replicated from scratch.
The copper roof was commonly applied to cars on high voltage lines. Not sure if the roofs were then grounded as a precaution to protect the car incase of a fallen wire. Walt Stafa
