Different operating sounds, such as oil and water being replenished or the sounds of opening and closing the sliding windows and the ventilation hatch on the cab, can be controlled digitally. It also has a controlled high-performance motor with a flywheel, mounted in the boiler. Six axles are powered. Traction tires are fitted. The chassis is articulated to negotiate sharp curves. The model has Boxpok wheels. The loco and tender have headlights and backup lights. The headlights will work in conventional operation and can be controlled digitally. The cab lighting and the illuminated number boards\/marker lights can be controlled separately in digital operation. Maintenance-free, warm-white LEDs are used for the lighting. A buffer capacitor is fitted. The factory-installed, speed-dependent, dynamic smoke exhaust can also be controlled digitally. There is a powerful speaker in the tender. An imitation coupler in a standard pocket can be mounted on the pilot at the front of the locomotive. There is a close coupling with a guide mechanism between the loco and tender. Steam lines on the front group of driving wheels are mounted to swing out and back with the cylinders. The metal handrails are separately applied, as are many other details. Figures of a locomotive engineer and fireman for the engineer’s cab are included. The locomotive is screwed to a presentation base to protect it during transport. Length over the couplers 42.5 cm \/ 16-3\/4\".\n\t\t\t\t\t\t\t\u003c\/p\u003e\n\u003cp\u003eNotes for operation: Although the locomotive can be used on curved track with a radius of 360 mm \/ 14-3\/16\" or larger, we recommend larger radius curves. Due to the overhang of the long boiler, any signals, catenary masts, bridge handrails, tunnel portals, etc. must be installed in such a way that ensures sufficient clearance on curves. Due to the high weight of the locomotive, the track must be firmly secured in position. The turntable and transfer table can be traversed by the locomotive but not turned or moved.\nProducts bearing the wording “Union Pacific” are made under trademark license from the Union Pacific Railroad Company.\u003c\/p\u003e\n\u003cp\u003eA matching US heavy-weight car set is available in the Märklin H0 range as item 43629.\nA DC version of this model is available in the Trix H0 range as item 25913.\u003c\/p\u003e\n\u003cp\u003eFind more Märklin explanation videos on our \u003ca href=\"https:\/\/www.youtube.com\/channel\/UCB-OmGaVsGnWkUFtRGIryKA\"\u003eYouTube Channel\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eSpare parts for our articles can be found \u003ca href=\"https:\/\/www.maerklin.de\/en\/service\/instructions-spare-parts\/spare-parts\"\u003ehere\u003c\/a\u003e in our spare parts search.\u003c\/p\u003e\n\u003cp\u003eOne-time series\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDigital Functions\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeadlight(s)\u003c\/li\u003e\n\u003cli\u003eSmoke generator\u003c\/li\u003e\n\u003cli\u003eSteam locomotive op. sounds\u003c\/li\u003e\n\u003cli\u003eLocomotive whistle\u003c\/li\u003e\n\u003cli\u003eDirect control\u003c\/li\u003e\n\u003cli\u003eSound of squealing brakes off\u003c\/li\u003e\n\u003cli\u003eBell\u003c\/li\u003e\n\u003cli\u003eGrade crossing\u003c\/li\u003e\n\u003cli\u003eEngineer’s cab lighting\u003c\/li\u003e\n\u003cli\u003eLetting off Steam\u003c\/li\u003e\n\u003cli\u003eNumber Board Lights\u003c\/li\u003e\n\u003cli\u003eAir Pump\u003c\/li\u003e\n\u003cli\u003eWater Pump\u003c\/li\u003e\n\u003cli\u003eInjectors\u003c\/li\u003e\n\u003cli\u003eLight Function\u003c\/li\u003e\n\u003cli\u003eRunning gear lights\u003c\/li\u003e\n\u003cli\u003eSound of Couplers Engaging\u003c\/li\u003e\n\u003cli\u003eRail Joints\u003c\/li\u003e\n\u003cli\u003eCab Radio\u003c\/li\u003e\n\u003cli\u003eWhistle for switching maneuver\u003c\/li\u003e\n\u003cli\u003eReplenishing sand\u003c\/li\u003e\n\u003cli\u003eReplenishing fuel\u003c\/li\u003e\n\u003cli\u003eReplenishing water\u003c\/li\u003e\n\u003cli\u003eSanding\u003c\/li\u003e\n\u003cli\u003eOperating sounds\u003c\/li\u003e\n\u003cli\u003eOperating sounds\u003c\/li\u003e\n\u003cli\u003eOperating sounds\u003c\/li\u003e\n\u003cli\u003eCompressor\u003c\/li\u003e\n\u003cli\u003eAuxiliary Blower\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Marklin","offers":[{"title":"Default Title","offer_id":45586308169904,"sku":"39913","price":1099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/0161\/8352\/files\/130099b9cea447132c68a3b748e5a70d1787756416.jpg?v=1789517307","url":"https:\/\/euromodeltrains.com\/products\/marklin-39913","provider":"Euro Model Trains","version":"1.0","type":"link"}
