Big Boy 4014 nearly complete fist time whistle blow April 27th, 2019

First whistle blow at 7:01.

It's a glorious day as Union Pacific #4014 blows it's whistle for the first time. It took 5 long years of work and millions of dollars spent, and now we see the giant come back to life. The steam crew put heart and soul into this locomotive working night and day sometimes 7 days a week.

Now we see the stunning results of so much hard work outside the steam shop in Cheyenne, Wyoming. Union Pacific, Big Boy, #4014 will soon be the Worlds largest operating steam locomotive. Weighing a astronomical 1,250,000 pounds, this locomotive will turn heads everywhere it goes.

In this video we see the steam crew slowly bringing the locomotive up to the 300 PSI operating pressure. Later we see one of the safety valves opening releasing excess steam. This was the first time the whistle was blown under steam.

The whistle may sound terrible at first but this is common for all steam locomotives. The steam is very wet and very saturated after a steam locomotive has been sitting for any period of time. Water is often in the whistle pipe and it needs to be blown out with dry steam. This can take anywhere from under a minute or several minutes.
