Interesting video. Thank you. Beautiful scenery.
Funny Thing is that I travelled to Switzerland again two Weeks later and wanted to visit the nearby Brienz-Rothorn-Bahn for another Video like this. This Video here was recorded at October 8, the Day after I visited SBB Historic Olten on a Workshop Day to record some Footage for my 100 Year old Electric Locomotive Video. I visited Olten again on October 21 to record the Ae 3/6 II in Action, but had to cancel Brienz because I was called by my Employer on short Notice (even Olten became almost impossible). Having another Video from nearby and two Weeks later would not only have shown another nice Railway, but also what a huge Difference two Weeks in October can make, when Autumn really kicks in.
@@Genius_at_Work We cannot always complete our plans but thanks for trying. Having ‘days off’ interrupted by work is just one of those annoyances that we have to put up with🙂! Cheers from NZ🇳🇿. Yes we have a funicular in my city and I did run over the old Rimutaka Incline Fell railway route back in the 1980s.
Good video, like
Fascinating, if you ever get a chance to film one being serviced/ repaired would be amazing.
Not there probably, but the French Chemin de Fer de la Rhune uses the same Type of Locomotives (SLM He 2/2), although with a different Electrical System; the Schynige Platte Bahn runs on 1500 V DC, the Chemin de Fer de la Rhune is one of four Triple Phase AC Railways left in the World, using 3000 V 50 Hz from a Bipolar Catenary. That's the Reason why I'm planning to make a Video there, to explain how the Power Transmission works (the third Phase is grounded in the Rails) and how the Switchwork inside the Locomotives allows a few constant Speeds for climbing the Mountain as well as regenerative Braking on the Way down. This is still going to take me a while, partially because I can't just travel at any Time to the French Pyrenees, but mostly because I want to demonstrate the Functions with some Experiments, for which I have to find two small and identical Slip Ring Motors, and a Place with Triple Phase AC Supply where they trust me that I'm not going to burn it down or cause other electrical Disasters.
@@Genius_at_Work I'll be waiting patiently with excitement. Your videos are really different to other engineering channels in a great way, i'm more than happy to pause and read text thoroughly and generally watch them thru twice - aways learn something new. I was wondering about the power braking system, redundancy safety mechanisms and power delivery for Funicular rail, thank you very much for replying.
Power Braking here is really easy. The Motors can just as well run as Generators, and the generated Power is "disposed" in Resistor Banks. In this Video, I recorded the Traction Motors while shunting into the Depot after going downhill, and it was quite toasty inside the Locomotive. Regenerative Braking is impractical with DC Systems, because the Transformer in the Substation could only feed AC back into the Transmission Grid and the Rectifier between Transformer and Railway Power Line only works one Way; it can't turn DC into AC again. The Triple Phase AC Systems use asynchronous Motors, which run undersynchronous when acting as Motors uphill and oversynchronous when acting as Generators downhill. Meaning to say they turn slower than the rotating Electromagnetic Field inside when acting as Motors, and faster when acting as Generators.
Btw. are Funiculars something different; a Funicular is hauled uphill by a Cable between the Rails, Rack Railways push themselves up with a Rack and Pinion System. There also are Funiculars with Racks (e.g. the Giessbachbahn also nearby to the Schynige Platte Bahn; check out my Paddle Steamer Lötschberg Video from 2020 to see that), but there it is used for Braking only. Rack Railways always have the Propulsion on the Train, in order to turn the Pinion Wheels. Funiculars usually are powered in the upper Station, but there also are some that don't have any Motors or Engines at all and simply rely on Weight, by adding Ballast Water to the downhill Car. This only works for short Distances, as on longer Funiculars (e.g. the Harderbahn in nearby Interlaken or the Bürgenstockbahn at Lake Lucerne), the Weight of the Cables far exceeds the Weight of the Loaded Cars and the System thus isn't balanced enough for a little Water to make enough Difference.
@@Genius_at_Work Ah so these are Rack railways, not funicular, but it was good to learn some use both. Thankyou for explaining asynch and oversynch to me so clearly. I'll happily watch the Steamer Lötschberg video again to see the Rack train that uses cable braking. Appreciate you taking the time to describe these systems, I look forward to more videos.
I am working on a video as part of a classical music recording. Would it be possible to license part of this video for use? It would be a low volume usage. I hope you can assist us.
No Problem, as long as you just use some Clips and credit my original Video
