Brilliant video. Fascinating how the wires stop on these bridges. I can see the bridge north of Heerenveen and also the one north of Akkrum ... but where are the locations of the other 2 un electrified bridges ??
Ah - mystery generated. Mystery soled. The train seemed to be moving rather languidly. So finally I decided to figure out how fast it was really going. The first measurement I took was counting off ten catenary poles with a stop watch. Then I used Google Earth to measure the distance for ten catenary supports in that region. That measurement mostly cleared up the reason for the low speed impression. Many other places in Holland have poles 55 meters apart or so. These are 67 meters apart. "Ah," methinks, "no wonder. But still..." I did the arithmetic and got 120 kph, or about 75 MPH, quite close to the road speed. The widely spaced supports just made it seem slow. Yes, past Meppel the poles seem to be closer together, about 64 meters. So the train LOOKS like it is going faster. Add that to the 14 road speed and the apparent speed increase is more than is the real case. I wonder why spacing varies so much. Perhaps it has to do with the traffic on that section of track? Nice ride. Fun tiny mystery, {^_-}

@@CabviewHolland In the 1960s? Um, ....That was VERY much a boys' club in those days, at least in the US. I'd have had the same trouble with trains I had with radios back in the day. I'd take them apart, figure out how they worked, and rebuild them "better" than before for my needs with parts I had. WW-II surplus radios tended to be somewhat odd in places due to parts shortage based substitutions. (And, after all, I am a WW-II baby. I'm smart. Daddy was a brilliant metallurgist who ran a government lab during the war. I think I picked up "The Knack" (see Dilbert) from him.) {o.o}
According to www.openrailwaymap.org the line supports up to 140 kph, so 120-130 seems reasonable for everyday operation :-) For a more accurate measurement I recommend using the mileposts/mileboards. Unfortunately these are quite small in Holland, so hard to spot in the video.
What is the meaning of the signal at 2:38? I tried google translate on the Dutch signal book, but the results weren't really explaining it to me; but then the Dutch signal book appears to be a little on the terse side of explanation, too. How to interpret the signals with two horizontal white(?) lights, and what happens if only one is shown (if I remember correctly)?
AfaIk these signals warn service crews and drivers that the track beyond is engaged by a train, notably in cases of poor sight. Then the lights flash alternately. Also the lights appear vertically mounted, it seems these flash for any train admitted to that track block, even the one you're in. Horizontally mounted I noticed flashing mainly for oncoming trains. I got this from watching cab rides, not from a signal book... Notably, these signals are no repeaters for a signal at danger that may show up around a corner. Repeaters show as iluminated white bars, horizontal if danger, slant if not. So these are NO direction indicators :-)
It's not for trains as such. It's for workers so that they can see if a train will come around a blind spot like a bridge/corner. They flash when a train is aprroaching.

This is an interesting issue. There is a parallel power line along with the contact and catenary wires.

From the train's point of view it would be like crossing a "gap" in a third-rail system. Traction power is of course lost, and the "hotel" systems will quickly "shed load" by turning off things like air conditioning. Lights, toilets and air systems would still be powered by batteries; these are capable of keeping things in the train comfortable for a couple of hours in case of stranding due to a power failure. Rather more importantly, because there is a physical gap in the overhead wire, the pantograph has to be physically lowered to cross it. There must be a special transponder on the track somewhere which controls this, and only trains which can understand that transponder (or which don't have pantographs) can use that line.
@@Kromaatikse the trains in the netherlands have something called a "nok "(or something like that) that makes them able to cross certain not all bridges with the pantograph raised but this system has to be disabled if the train crosses the border into Belgium or germany And with third rail system in our country even when there is a gap the are multiple connectors like one on each truck or bogie (which one you call it) on each side so the subway never loses power unless the gap is bigger than the subway
@@Kromaatikse The pantographs of Dutch trains actually don't lower when crossing these bridges. All Dutch trains have a thing called a "stuit" build into the pantograph which prevents it from raising to high when power lines stop. At the other end of the bridge there are guiding rods which press the pantograph back under the power lines. Also most trains have a way to keep all their high power systems going while there is no power from the power lines. If the train has the ability to ED brake (brake using the traction engines), we will brake very slightly. This turns the engines into power generators essentially and we use this power to keep all onboard systems going including AC. The train in this video however does not have the ability to ED brake and will lose power to all high voltage systems onboard.
@@arfanvlk9351 Third rail is more common in the UK. The front and rear coaches on EMUs both have shoes which are electrically tied together, so "section gaps" dividing power supply zones have to be longer than any such unit (usually 4 cars, 80m). A train running into one of those under full power makes a spectacular arc flash. The Tube has a different system in which there are no lighting batteries and the shoes are not tied together, and the lighting in the train has half the lamps powered from one set of shoes and half from the other - in some of the older Tube trains, you get briefly left in pitch darkness when passing certain junctions which "gap" both sets of shoes at once. Meanwhile, the 25kV AC system has regularly spaced "neutral sections" dividing areas that are powered from different phases of the National Grid (to spread the railway's load evenly between them). Electrically speaking, passing those is very similar to crossing those bridges. However, there is no physical discontinuity in the cable, only a short section of unpowered wire with an insulator at each end (it prevents an arc being drawn between the two phases by the passing train).
