i am building a two level shelf layout in a two car garage,with a branch into the garden. thats right on30 in the garden. class one rail roading which allows me to run all my bachmann equipment,all steam with pass & freight turns. end a..the brewery,3 heljan ho kits bashed into one complex. end b the barge.. to points off the layout. end c the mine. end d the saw mill.
b,c & d are scratchbuilt with interiors where required.this is an operational switching layout. am starting to play with dcc,now it comes onboard.
there is a switchback between levels.each shelf    is 20 foot long.the branch,up to 25 feet,keep you posted. photos to come

dear michael,i had the same problem with my climax. you will find that the drive gear has parted company with the drive shaft knurling. when the loco is dissassembled,a small drop of superglue should solve the problem. mine has worked ok since this overhaul. maybe bachmann can modify the gear to shaft application.i also live in australia,melb to be exact. check with buffer stop who did the repair,regards graeme pendlebury
