RBMN 425 Northbound through Tamaqua Tunnel

Personally the loudest thing I've ever heard.
Details: RBMN 425, 4-6-2 light pacific locomotive built by Baldwin Locomotive Works in January 1928.

Nice shot man, she’s running great!

Neat video. I like the headlight effect.

[@timdouglas8800]

Gotta love a steam engine. There's nothing more special than that.

I presume that consist is more than 425 could handle comfortably thus the diesel backup.

[@ReadingRailFilms]

your assumption would be correct. Steep grades on the Reading division require deisel backup for 425, especially with wet rails, which they were the day this was filmed
