Rokuhan is working on a viaduct series with straights and curves and double track and single track with adjustable piers to ramp up or down from Viaduct. Viaduct will be able to take track from other manufacturers such as Micro trains or Marklin, Crown, Platz but limited to these manufacturers. This elevated Viaduct is representative of elevated right of ways used by Shinkansen in Japan. Rokuhan welcomes comment on this and any other product they are working on or have produced. Rokuhan also has a newer design for thier track feed which will work with this Viaduct and on double track main. it will fit between the two lines on 25mm spacing something the original version could not do. Present design is for 110mm straights, single curves 195 and 220mm and double track curves 195 and 220mm. straight 110mm sections can be opened up to take double track main. No plans yet for elevated stations or bridging with steel truss or arched steel. Rokuhan contact page is here http://www.rokuhan.com/english/contact/index.html best regards Garth
