Testing Pattern?

[R44 CNG 473]

 

 

1. Does this happen to every train that comes out the yard?

2. For a certain reason?

3. Only NTT's or R142's?

 

Thanks!

I cannot answer those questions, but that is the weirdest video I've seen.

 

I lol'd when the T/O was nodding at the camera like "Oh, yeah!"...

That T/O looks familar......

I'm not sure if it does that on the B Division NTTs but that looks correct for the R142A:

I am sure that is a normal system test. When the locomotive systems are turned on, It would run through the test to make sure that it can load all the routes correctly.

So...why did an (8) route display? No such thing.

That's pretty cool, too bad we couldn't see the though.

Yes that's standard. It's a test pattern used to make sure all the electronic connections are working throughout the train and all signs are displaying uniformly.

 

They do use something similar with the R44/R46's, so it's not just NTT's. The one used at Coney Island displays all C's then changes to all I's

 

As for the person asking about the 8 route, there is no 8 route, it's part of the test pattern. For a test pattern to work it's important the sign change so that crews can make sure all the signs are updating at roughly the same time. In that particular case the route readout was changing number as a "count up" part of the pattern and 8 just happens to be after 7.

 

It doesn't necessarily happen to every train that comes out of the yard but test patterns are run on all the cars every so often. Most times it's done is right after an add (coupling) to make sure that all the electronic connections are working right between the two recently coupled sets.

Either a transit employee was taking the video or a transit employee was with him while the video was being shot. This is because there is radio noise. Because of this, the t/o was nodding at the person with the radio.

...but what about looking directly at the recorder?

Well, a person could easily purchase a scanner. This would allow them to listen in on transit communications.

Perhaps the person with the TA radio was standing right next to the person doing the recording?

Lmao, you always have an answer, don't ya? B)

That T/O looks like one of my friends looks like David
