4-12-2 Running On Air

The big 4-12-2 running on air back in February of 2022 running on 150 psi of shop air on short stretch of track laid in the shop

Beyond cool. I've never seen anyone take accurate modeling at this scale seriously, so it is AMAZING to see such a fantastic engine of this size! Must be a blast to be part of the crew!

That's fascinating, at this point, this is a real working locomotive in every sense, it can pull passenger cars and do real work, and with that wheel arrangement it probably has a LOT of torque!

Way to go guys. Alex looks like he is right at home in the cab. Darrell looks like he is using his ears and eyes searching for any corrections to be made while moving on the test track.

This is awesome! The level of skill and dedication to make something like this is commendable.

Brilliant! On my railfan trip (from UK) to California in 2008 I saw the full-size 4-12-2 at Pomona. And Big Boy 4014 was in the same yard! One of the great days. Many thanks.

Talk about the WOW Factor. What an amazing project! The workmanship is just beautiful.

At first i thought it was small due to the angle of the camera but i am ever more impressed by the scale of this thing!

[pezer]

This is insane! The amount of time, money, work, skill, knowledge, and teamwork to create such a delicate, yet strong and heavy model is certainly an accomplishment to be proud of! Im very intrigued and have many questions to say the least.

Потрясающая работа!! Создать такое могут только по настоящему увлечённые и сплочённые идеей люди с большой буквы. Колёсная формула этого минипаровоза вызывает только чувство огромного восхищения. Ребята вы СУПЕР 👍👍👍👍!!

Bloody MASSIVE! Is this the fabled 15" gauge I've only heard in myths and legends? This behemoth certainly lives up to them, that's for sure! I can never look at 7.5" gauge stuff without thinking it's tiny anymore, great work!

[bbviper]

these guys must have a HUGE friggin christmas tree to run this under!

[theq]

im about 5'2 (yes im a grown ass man), bet i could stand up comfortable in that thing with a normal footplate its HUGE
congratz on all the hard work paying off your machine is gorgeous

[wwebtime]

That's whistle is gonna sound great outside with some echo effect! Great Job!

[cdnpont]

This lets you see how smooth these engines really are. Thank you.

[germanfragger]

Holy shit that Whistle is perfect got goosebumps!

[dennismaloney]

As a pipefitter who used to rebuild steam-reducing stations and other components, I always used air to test the performance.

[gordonsnell]

DAMN!! Love that whistle on it, VERY nice 🙂🙂

[michaelboykin]

Mind Blowing detail. Much respect to the design and build team.

[rogerhupp]

This is one of the coolest things that I’ve seen in my entire life!

[titan_redeemer]

Absolutely beautiful piece of machinery👍
