Thank you for viewing. Here is a description of the Rokuhan Z Shorty series powered chassis, with confirmed operation. It is unclear whether this is the SA002-1 powered chassis (Shinkansen type) or the SA001-1 powered chassis (Normal type / exposed bogie type). It is likely the "Shinkansen type" SA002-1, but please make your final determination based on the photos. Tested with both Rokuhan and Märklin Z gauge. It runs strongly in both forward and reverse directions. Everything in the photos is included, but the rails are not included. This item has been tested and confirmed to work, but it has been handled by a person, so please understand that it is being sold as-is, with no returns or exchanges. marklin railway
