R179 Testing on the D, F, and G lines

Recommended Posts

Some more clips of the R179 test train. Many of the locations the train is seen operating on are highly unlikely to see R179s operating in revenue service. Some are unlikely to even see the cars on non-revenue moves as well.

Enjoy, and please subscribe!

Is it me or does the 179 have a really annoying, high pitched squeal? It seems to go on as long as the train is in motion, not just when it accelerates

That's because when it's rolling through the station, the T/O either has the master controller in min brake or min accel. If he actually put the controller in coast, you wouldn't hear the propulsion; just the rail noise, air bags, and the third rail shoes.

Thanks! Would the sound be present if the controller was at a higher setting, like max power?
