How is MetroNorth rebuilding Park Ave Viaduct without stopping trains?

Built in 1873, the Park Avenue viaduct carries trains from the Harlem River into Grand Central Terminal has faced challenges in recent years due to wear and tear from constant use and exposure to the elements. As a result, there has been a need for reconstruction and restoration to ensure the viaduct remains safe and functional for commuters and residents alike.
The Park Avenue viaduct carries all commuter trains from the northern suburbs into New York City.
The reconstruction of the viaduct must be done on weekends and late at night to avoid conflict with the many, many commuter trains. The vertical metal piers supporting the tracks are weakened to ageing and need to be replaced before they fail. The solution they came up with to solve this problem is to cast new concreate pillars under the viaduct. Once the concrete hardens, they will use two huge cranes to lower the track girders onto the new pilings.
The two cranes sit on the road surface of Park Ave straddling the 4-track wide right of way. The cranes can come apart to move them. This type of crane is used more for intermodal container movement. The wheeled base sections are moveable separately and are very maneuverable. When I visited one of the cranes was dismantled.
Over the course of summer, the whole section of the viaduct supported by metal will be changed from the old metal support to new concrete supports.

@@JSquaredJJYT Oops did I misspeak? I would not be surprised if something dumb creeped in. Thanks for keeping me honest.

I saw one metronorth train going to Gran Central from Westchester with a blue and yellow livery, dont know if it said RN or RE it went ny at like 80mph in front of my building

@@PatricioGarcia1973 Metro North has wrapped two of their engines in a blue and yellow scheme. Conrail and Penn Central. It was possibly one or the other of those.

Yeahhhhhh metro north

[@este_Pandy_Projects]

I’ve always been a big fan of Metro North. Most of the track they run on is the most beautiful in the country. I also like that some of the older cars still have individual names. Very old fashioned but fun to see.

Genesis are made by alstolm

@@IsrealiAvia Genesis are made by GE.

[@IsrealiAvia]

@@este_Pandy_Projects sarcasm cause you said "alstolm p32"

[@este_Pandy_Projects]

@@IsrealiAvia I don’t know why I said that. You are right. I know they are GE. I first saw them back in the 90’s on one of their first assignments on the Autotrain. They had a speed blur stripe and they were called AMD-103. It was a dumb mistake in my video.

[@dapperdonny4051]

Metro-North uses M-7A and M-3A. LIRR uses M-7, M-3, M-9

[@c9917k]

Don't forget the M8.

[@dapperdonny4051]

@@c9917k My bad.

[@este_Pandy_Projects]

[@leecornwell5632]

Don't forget about the M9AS for metro North railroad is definitely gonna to replace all the M3AS on the metro North. Including the chargers for metro North and the Long Island railroad.

[@este_Pandy_Projects]

@@leecornwell5632 yes absolutely get those final runs.

[@monkeystuff661]

[@este_Pandy_Projects]

Haha well Madison if you want to go to Long Island.

Dude you need to get better audio, I can't hear your voice like at all

[@este_Pandy_Projects]

Thanks I don’t know why this is so low. Every time I think I have it figured out something like this happens.

[@Santiago-lb5md]

@@este_Pandy_Projects must be your headphones then?, because they can be tricky sometimes.
The best thing that you can do is record your audio directly from your phone, the mics are pretty decent for beginners and it will help you a lot. Secondly, you need to constantly watch the audio levels on your editing software of choice, ideally you need the audio to peak on 6-4 DB. Almost at the top for a clear voiceover.

[@este_Pandy_Projects]

@@Santiago-lb5md That's a great trick. Thank you so much. The edit software I am using has green yellow and red levels. I was trying to keep it in green mostly but when I transfer to YT it gets so quiet.

[@Santiago-lb5md]

@@este_Pandy_Projects yeah, that happens, that's why the audio should be at least being somewhat yellowish and at the levels I pointed!, good luck on the next video!

[@este_Pandy_Projects]

@@Santiago-lb5md Thank you. Great advice!
