"DMV (Dual Mode Vehicle)" that can run as both a railway and a bus

"Railway Technology Exhibition 2010"Was the information of" DMV (Dual Mode Vehicle) "that JR Hokkaido was exhibiting.

DMV is installed to run the railroadOrbit(Rail) and the car to runroadIt is unnecessary for districts where the railway network is developed and there are many users, such as the metropolitan area, but in areas where railway users are small, cost reduction and trunk of local line activation, "dream It is expected as a 'ride of'.

The first prototype car in 2004, the DMV whose second prototype car is being manufactured in 2005, what kind of feeling is it?
JR Hokkaidobooth.


The idea of ​​"Is it convenient if there are both railway and bus vehicles?" Is quite old, and various types of trial and error have been carried out, such as those traveling with rubber tires and running on iron wheels. However, the rubber tire drive type had problems with tire strength and traction performance, and problems with the steel wheel drive type taking time to change the mode were problems, neither was able to reach full-scale sales. However, in January 2004, JR Hokkaido succeeded in developing "DMV".


Due to the declining birthrate and aging population and motorization, local railroads and buses have become difficult to manage. In order to solve this problem, "DMV" was developed as a low cost and convenience-enhancing vehicle. It seems to have been put into practical use for the first time in the world as for business use.


"Guide wheel serif steering system" for smoothly passing curves, "rear axle heavy distribution control system" which balances driving stability and driving force transmission, "DMV" for ensuring the driving wheels to ride on rails "Rear Rubber Tire Drive System", "Hydraulic Mode Change System" that realizes quick mode change between railroad traveling mode and railroad traveling mode, "Mode interchange system" realizing reliable mode change, etc. are installed .


"DMV" has steadily evolved since the first prototype in 2004, and the prototype car "DMV 921" completed in 2009 and the prototype cars "DMV 922" and "DMV 923" completed in 2010 have the capacity limit It is increasing than before, improving vehicle body vibration and improving energy saving performance.


As an example of utilization of "DMV", it is considered to avoid road congestion, to take advantage of the scheduling nature of the railway, an alternative route of railway which is still planned to be extended, a detour operation when the railroad is inoperative due to a disaster, etc. It is done.


The introduction of DMV to the community that is dependent on the car means that a new transportation system will be born.


As expected there was no real thing in the hall, models were exhibited.


It is equipped with both rubber tires and iron wheels like this.


When traveling in a railroad this way it is running on a rail with iron wheels.


Running in Shizuoka PrefectureSanyan RailwayIn addition to conducting a running test since 2006, in Gifu PrefectureMeichi RailwayIn Shizuoka PrefectureTenryu Hamana RailwayA demonstration experiment was held at.

Further introduction is being considered in various places, and if it spreads it may be a new form of local transportation.
