Our club (www.wimrc.ca) is planning the introduction of a portable hinged lift-up module to reduce the need for duck-unders, which are becoming more onerous as some of our members grow in size (unfortunately), and all of us age - pitiful cries of aching backs and knees are heard every session! The self-contained module would feature a four foot long hinged deck just wide enough to support two or three through-tracks, supported by vertical sections at each end (so as not to depend on adjoining modules) and with a floor level bottom channel acting as a conduit for the DCC Loconet, track power bus and 110 volt utility cables running between the adjoining modules. A concern we have is that the module is likely to be heavy, probably more than 60 to 70 lbs and a bit of a monster to move when going to and from shows. We'd appreciate hearing any comments, recommendations or references. Thanks!
