Walthers unveils four new models in April 2026 Express video

Walthers packed four fresh releases into a 2-minute, 15-second New Product Express video, and the quickest read on the lineup is simple: this is a roster-building month, not a single-headline month. The mix reaches across premium freight, modern power, and two contemporary freight cars that can slide into everything from intermodal corridors to general merchandise service.

The standout for many modelers will be the WalthersMainline General Electric ET44AC Evolution Series diesel. That is the most consequential addition in the group because a current-era six-axle road unit changes a roster faster than any individual freight car, especially for layouts set in the 2010s and later. WalthersMainline is aimed at realistic locomotives and rolling stock for classic and contemporary eras, with metal wheels, couplers, and optional DCC and sound, so the ET44AC fits squarely into the kind of operating sessions where modern power matters as much as car variety.

Walthers also used the video to put a WalthersProto 56-foot Thrall all-door boxcar in front of freight-car collectors and era modelers who want a more prototype-specific piece. Walthers says the design dates to the late 1960s, when it was developed for lumber and weather-sensitive building materials, and many cars stayed in service into the early 2000s. That gives the car a long operating window, which is exactly what makes it useful for modelers trying to anchor a late-transition or early-modern freight train with something that feels right on the track.

The remaining two releases lean hard into contemporary freight traffic. The WalthersMainline 72-foot modern refrigerator boxcar is based on prototypes introduced in 2019 and is described as a nationwide workhorse for frozen foods, fruit, vegetables, and other perishables. The WalthersMainline 60-foot Gunderson Plate F boxcar with horizontal side posts fills a similar practical niche, with Walthers calling it a modern-era mainstay for lumber, canned goods, appliances, and other high-priority freight. Those are the cars that layout builders can use to bulk out operating schemes without straying from believable prototype traffic.

Walthers framed the April releases as limited-quantity, one-time-run offerings on the product pages, which makes the video more than a teaser reel. It is a fast preorder signal for anyone trying to decide whether to add a detailed premium boxcar, a modern road diesel, or a pair of flexible freight cars before stock tightens.
