Choosing among model locomotives & rolling stock comes down to a practical fork: do you want a lead unit with a named railroad identity, or more cars to build out a freight consist? The Athearn and Micro Trains choices are aimed at different jobs, so the right buy depends on what your layout needs next-not simply which listed price is lower.
Quick verdict
Choose the Athearn KCS SD40-2 if your next addition should be a powered diesel with a specific railroad identity. Choose the Micro Trains Box Cars if you want a group of freight cars for a consist or collection. The listed prices differ by $31, but the role each piece fills is the bigger separator.

Where each product wins
Athearn wins for railroad-specific display
The Athearn earns the edge when the appeal is a Kansas City Southern road number and a body with visible detailing. The white shell, red KCS lettering, metal handrails, and roof fan make its identity more specific than a generic freight addition. Its ready-to-go/pre-built status keeps the choice centered on an established piece that can serve as a named railroad focal point.
Micro Trains wins for adding freight cars
Micro Trains has the clearer case when the project is expanding a freight consist in one purchase. The lot's multicolor transportation theme provides a defined group, while the pre-built format keeps the emphasis on adding rolling stock rather than assembling a locomotive. This is the better role match for a shopper who wants several freight cars together, not a single powered unit.
Product notes
Athearn KCS SD40-2 Powered Diesel Locomotive
The Athearn choice is for the shopper who wants a named road locomotive with a clearly defined visual package. Kansas City Southern styling, road number #678, crisp white paint, red KCS lettering, metal handrails, and roof-fan detail give the piece a specific display identity. It also includes standard horn-hook/knuckle couplers and is ready to go/pre-built, supporting a straightforward addition for someone seeking a powered unit. The limitation is packaging: the original blue Athearn box shows shelf wear typical of age. That matters if the original box is part of the collecting appeal, even though the locomotive itself remains the focus of the purchase.
Micro Trains Box Cars
The Micro Trains lot makes sense when the priority is a ready-to-go group of freight cars rather than a powered engine. It contains pre-built box cars with a multicolor transportation theme, giving the purchase a clear collecting or consist-building purpose without shifting the focus to locomotive detailing. The limitation is the format itself: box cars do not provide locomotive power, so they cannot fill the same role as the Athearn SD40-2. The lot is a focused freight-car addition; choose it when rolling stock is the goal, or choose the Athearn when motive power is the requirement.
Final choice by use case
- For an HO layout: choose the Athearn because it is identified as HO and 1:87, with a powered-diesel role.
- For an N layout: choose the Micro Trains set because it is identified as N and 1:160, with box cars for freight service.
- For new condition: Micro Trains is listed as new, while the Athearn is listed as used with a C-5 Good grade.
The decision is straightforward: match the scale first, then choose between a powered locomotive and a freight-car group. Athearn is the direct locomotive choice; Micro Trains is the direct rolling-stock choice.
