Strasburg Railroad 475 June 2013, part 2 

The engines now have surface blow-downs, which can be used safely on the move. This reduces the need to regularly use the conventional mud-rung blow-down.

Is that the only locomotive running on that day?

no more blow-downs in paradise?! it looks like strasburg is not taking as care of their locomotives as good as they used to...less years for 475,90,89

is this a female i hear doing the lecture?!
