Just read a Dealer's disclaimer on restricted use of one of Marklin's newest Z creations: From this: "In 1978, a Märklin Z scale locomotive pulling six coaches made its entry into the Guinness Book of World Records by running nonstop for 1,219 hours, and travelling a distance of 720 km (450 mi) before the train stopped due to failure of the motor." (https://en.wikipedia.org/wiki/Z_scale) To THIS! Marklin 88025 Klv 20 Powered Rail Maintenance Vehicle VW Bull Rail Car / VW Bus for Z scale Dealer Disclaimer: "This is a new powered rail car. It is equipped with the new "bell-shaped armature" motor - so it is NEITHER a 3-pole nor a 5-pole motor. NOTE: This unit cannot run continuously - it must be used only in short spurts. You also must use a Z scale rated power pack. No refunds or exchanges for any misuse outside these parameters." Zie Panzer's are now made of Zie Plastic. Sigh.
