Yes.There are 6 positions. OFF, RUN down, NOTCH down, HOLD, NOTCH up and RUN up. At low speed you would use the individual notch up to add power then at higher speed use RUN up (or down) to control the power.
The only time I rode in an 87, was 87 019 from Euston to Wolverhampton. I regularly ride 86s and 90s on Anglia. I have also done a 91 from Kings Cross to York, and a 73 from Victoria to Gatwick. Plus driven a V63 / 630 "Gigant" in Hungary !!
Class 87s are absolutely awesome locomotives I would rather have haulage behind them rather than the pendelinoes and the plastic unit's such as the class 801/803/proper locomotives
Hi, love all the different noises going on here. (I remember being fascinated by the 87's & 86's for the first time in 1980 Euston Station on route to Preston Lancs) -- Q? = were all transformer cooling fans switched on/off automatically???
Real country music here Respectfully dressed No ghetto apparel County pop sucks County rap sucks If it doesn't look and sound like this, it's not right and it needs to go away and go by another name other than county
Incredible machine. Some of these 87s when in good condition could regularly put out well over 7000 hp. A very simple locomotive, no computers just a tap changer transformer and four traction motors, and enough power to pull the top off a mountain.
Hellfire tapchanger action! Love the neutral section breaker noise with the 'engine' room door kept open. No simple pull on power controller and let it all happen; drivers really needed to 'drive' these AC locos.
@@theblacktrainboy373 The tapchanger draws current from (or indeed 'taps into') the main transformer for the traction motors. It's basically a widget consisting of electrical contacts of differing voltages operated by a camshaft mechanism. On these locos there are 38 taps. The tapchanger is manually controlled directly from the driver's desk where, by to-and-fro of the master controller, he does all the 'notching' to increase/ decrease/cut voltage in steps as required. Tapchangers are ancient history now. All locos built since the 1980s have automatic 'stepless' control using new-fangled stuff called electronics(!)
@@ChangesOneTim also the traction motor sound since 2007 I was 3 at the time I'm mainly around Tottenham hale and the class 317 have the same traction motor sound as the 87 and many other trains like class 321 and 319 I don't get it but i wish I could see these trains in real life down in North London there are no exiting trains besides alexandra Palace
@@theblacktrainboy373 All recent trains have 3-phase AC instead of the traditional DC traction motors. DCs have the good old rising note sing-song compared to the AC's pyschedelic-style random whining
Oooh, I love that satisfying clunk as the breakers open/close through the neutral section and the fans powering up again. Also the electrical hum when the handle is held in 'run up' - she's definitely drawing some amps! This is the perfect '87 video. You get just about every sound they make. I miss them so much.
As a former UK railwayman with noise induced hearing loss I'm curious to understand what noise levels a driver would be exposed to in an 87. Listening even in this video gives the impression that it is loud and a driver has no hiding place to get away from it. The AC locos sounded great when those fans whirred up but at what price?
It's the power controller. Used to run up or down the tapchanger, a device that varies the power output from the main transformer to the traction motors.
God Bless Texas! Sure do love this great dance music...especially that upright bass, steel and twin fiddles...guess that pretty much means I love it all!
This video is very interesting for me, I liked it because it was not in Indonesia, I have subscribed to your channel, visit my channel and subscribe train behind 😁 thanks, Greetings from Indonesia Railfans
+Celtic Saint Some trains have them for communication, so if a car stalled on the track they would call the phone and warn the train o tell them to stop
Jake is a breath of fresh air in the Country world, and his steeler, Rick Price is the best steel picker to come down the pike since Lloyd Green, John Hughey or Tom Brumley. How i wish mainstream America would wake up and kick the pretty boys of Gnashvegas to the curb, and bring out some real Country, like Jake and the boys do.
It's in England on the West Coast Main line North: Departure from Royal Mail supply on direction by Carluke (first station on movie) at Carstair and Carlisle.
