Choosing model locomotives & rolling stock can be tricky when one choice is a named, powered HO diesel locomotive and the other is a battery-powered steam train set with freight cars and track. The useful decision starts with scale and format: the Athearn centers on one specific locomotive, while the Electric Steam Train Set brings several components together at 1:200. Use those differences first, then let condition and price settle the choice.
Quick verdict
Choose HO Athearn Kansas City Southern SD40-2 Powered Diesel Locomotive KCS #678 if you want a specific powered diesel with Kansas City Southern identity and HO scale. Choose Electric Steam Train Set Freight Cars Railway Track Model Toy Collection if the priority is a pre-built collection with locomotive, freight cars, track, and battery power. Neither is a universal substitute: their scales, power formats, and product focus are different.

Where each wins
HO Athearn Kansas City Southern SD40-2
The Athearn locomotive wins on specificity. Its title identifies Athearn, the SD40-2 model, Kansas City Southern Railway, and road number KCS #678. That makes it the direct match for a shopper searching for a particular road name and locomotive designation rather than a broad train collection. The mechanical powered unit, six-axle drive trucks, metal handrails, roof-fan detail, and horn-hook or knuckle couplers add further concrete reasons to focus on this choice. Its appeal is centered on one defined HO locomotive and its railroad identity.
Electric Steam Train Set Freight Cars Railway Track Model Toy Collection
The Electric Steam Train Set wins on package definition. The included format is clearly stated as a locomotive, freight cars, and track, giving model railroad rolling stock shoppers a straightforward grouped collection. Its title also identifies an electric steam train set, while battery power supplies a distinct operating format. The 1:200 scale should be treated as its own selection criterion rather than compared as a higher or lower specification against HO. This set is the clearer choice when the components gathered together matter more than a named railroad locomotive.
Product notes
HO Athearn Kansas City Southern SD40-2 Powered Diesel Locomotive KCS #678
The strongest reason to choose the HO Athearn Kansas City Southern SD40-2 is its collector-specific presentation: white paint, bold red KCS lettering, cleanly printed #678, metal handrails, roof-fan detail, and the original Athearn "Trains in Miniature" blue box. Those details suit a shopper who wants a defined railroad locomotive with a recognizable road number. The limitation is equally specific: the unit is marked Used with Grade C-5 Good, and the box shows light shelf wear. That makes cosmetic condition part of the decision. Assembly is Ready to Go/Pre-built, so the appeal is the finished locomotive and detailing rather than a build project.
Electric Steam Train Set Freight Cars Railway Track Model Toy Collection
The Electric Steam Train Set suits shoppers who want a new, ready-to-go model toy collection rather than a single named diesel designation. It is marked New and Ready to Go/Pre-built, while black is the stated color and plastic is the stated material. Those attributes provide simple filters for shoppers who care about presentation or construction material. The concrete limitation is the plastic construction, which may rule it out for someone prioritizing a different material. Its steam-train wording also gives it a different character from the Athearn diesel. Choose it when a pre-built steam collection fits your hobby plan better than a specific KCS locomotive.
Final choice by use case
- For an HO scale locomotive search: choose HO Athearn Kansas City Southern SD40-2 Powered Diesel Locomotive KCS #678. Its title and 1:87 scale identify the exact format, while the Kansas City Southern road name and KCS #678 designation provide a clear collecting target.
- For a pre-built train collection: choose Electric Steam Train Set Freight Cars Railway Track Model Toy Collection. The locomotive, freight cars, and track are grouped together, with battery power and a 1:200 scale.
- For a price-led decision after those filters: the Electric Steam Train Set is listed at USD 32.20 versus USD 61.00 for the Athearn locomotive. Choose it when its scale and steam-set format fit; otherwise, the Athearn's specific HO and KCS identity justify choosing the focused locomotive.
