2023 RailKing O Gauge Halloween Series Announced

February 21, 2023 - M.T.H. Electric Trains will be releasing several limited-edition Halloween releases beginning this Fall including an ES44 Diesel locomotive and matching caboose, a Bump-n-Go Trolley and several complementing pieces of rolling stock. The Halloween-themed items continue a trend M.T.H. began back in 2008 and these 2023 releases are a great way to add to your own spooky collection of past cars, sets and buildings. Each of these offerings is expected to begin shipping to M.T.H. Authorized Retailers in September 2023.

The top-of-the-line RailKing Imperial ES44 diesel headlining this year's offerings features a full range of locomotive sounds recorded from an actual ES44AC. Outfitted with two powerful flywheel-equipped motors, all-metal wheels and gears, and our revolutionary Proto-Speed Control, the ES44AC will haul long freights at any speed from a crawl to full throttle. Remotely activated front and rear Proto-Couplers allow you to pick up and drop off freight wherever you like. Additional Imperial features on the ES44AC include operating diesel exhaust smoke, flashing LED ditch lights, and operating LED Charging Lights. When paired with the matching LED adorned caboose, you'll have one great looking Halloween train!

Check out each of the offerings in the list on the left.
