  1. Imho it looks more like a metro than a train service, but at least the route allows pretty high speeds due to being mostly staight.
  2. Quite a normal sight on some lake Balaton limited expresses in Hungary. One of the reasons many of these sets are using multiple half baggage combine cars. The most i've seen have been 9 cars with 3 combines (designated bicycle cars) and one full baggage, 50% of the train. On the other hand once when the normally 6 car north shore Ladybug resort limited express (1.5 hour non stop to the lake, then all stops along the coast) was ran with a lone desiro railcar (ok it does look like a ladybug), it was a really hard game of tetris to pack all the people and bikes in. Then gradually unpack them at each stop. I think the Boso bicycle train aims at the same tourist market. On the other hand, having two bikes for commuting is a real testament to japanese efficiency. This gives the highest commuter density and efficiency of all possible solutions.
  3. He did notice something just didn't care that much. On the other hand if that nosecone fully detached and got under the wheels, and would probably cause a derailment at 300 km/h, that would have been a bad thing and not just for the driver. Maybe hearing it only is good for his mental health, but not checking afterwards was dangerous and will probably cost him his work. The same applies in most countries if you hit something on the road and don't stop to check what or who was it.
  4. I think it's a question of tradeoffs between ease of maintenance with the exposed gears and increased time between maintenances with the gear protection added. Personally i think that since dust is bad, not just for the gears but the exposed pickups and other parts (or even for the scenery), keeping the layout room dust free is one method and removing the dust from the tracks before each running session is another. Both make dustproofing the locomotives unnecessary, but require more of work elsewhere. For running at exhbitions and on various other dirtier layouts, dustproofing is a good strategy.
  5. This is when i start to think if the set was shortened to a minimal working size (3 or 4 cars), then the rest of the cars could provide spares for a very long time of museum operation. After that, the set would be old enough to be a nice static exhibit.

    Kato 113 motor car derailing

    It could be a mechanical problem, like dirt in the transmission that prevents the bogie from rotating freely. You could check it manually that if you power the good bogie, you can rotate the other one freely. The other possibility is that you are trying to run a Kato 113 on Kato Unitram points and curves. Afaik only the Tomix 113-s are able to run on R150 curves and points.
  7. Fleischmann decoders are DCC compatible. The only problem i've found is that they have a very high analog conversion mode threshold. If the DCC voltage on your layout gets below 12V, they stop responding to DCC signals. One thing you could try is to disable analog conversion mode. For programming, just try to use the H0 voltage levels option on your Digitrax central as many of these decoders seem to be designed to work on H0 systems. On the other hand, i was able to program them using program on main mode too.

    Takara Tomy Linear Liner

    No, it's an actual maglev. The track has static neodymium magnets that repel the magnets in the train. A hall effect sensor in the nose senses the next incoming track magnet and generates the timing pulse for the train electromagnets to change polarity. This pulls the train along the static magnet chain in the track. Side guidance is by rollers, pretty much how the backup system works on the 1:1 prototype. (which is also steered by magnets during normal operation, but lands on rubber wheels in case of power loss) Generally you have to push the model over one magnet by hand to start the self regulating control system. Top speed is limited by the battery power remaining and the magnetization speed of the drive coils. Afair the japanese ad video explained this with drawings.
  9. I did some googling too and it seems that the buses have a 5,800 mm axle distance. That's 38mm in 1:150 and the minimal size of the BM-03. But the bus has a short looking overhang at the back, so i'm not sure a BM-03 would fit it. The BM-02R is 35mm, which is 3 mm shorter.
  10. I know it's a trolleybus, not a conventional one, but is it possible to motorize the new Tomytec Kanden tunnel trolleybuses? If yes, which type of chassis is good for them? I'm thinking along the lines of using a battery powered Tomytec chassis with the plastic current collectors replaced by working ones and live overhead wires.
  11. The metal joiner is pulled off carefully from the end of the metal rail and the insulating plastic joiner is slipped on instead. It's iportant to not break either and to protect the plastic stud in the roadbed.
  12. Looking at the old pictures and google street view, it looks like some of the bridges in the area have been kept and used as overpasses for the cars that fill most of the old canals as many of them have been converted into open or covered over expressways. One example is what is labeled as the Yaeshu route and runs right inside the old Edo castle outer moat, the one that went right next to Tokyo station. It enters under the water level at the Sumida river and exits onto the overhead ramp just north east from Yurakucho. At least one underground Tokyo station parking lot enterance seems to be connected to it. What surprises me is how much of this infrastructure is under the water levels of the old canals and actually under the normal water level of the Sumida river. And there are subways below all of this. For the old Shimbashi bridge, where one pillar still stands, there is a mysterious bump in the road under the highway, that follows the arch of the old bridge:
  13. In theory it's in the railway museum in Omiya, but i'm not sure if it's exhibited or in storage.
  14. Actually Tomytec makes curved side platforms for 280 and 317 mm curves. In this case the maximal inner and outer overhang has to be calculated for the rolling stock that will be in use, including the dynamic envelope of the moving cars. For constant radius curves, these two values will also be constants from the track centers.
