Choosing model locomotives & rolling stock comes down to one practical question: do you need more freight cars, a powered locomotive, or a package that includes a train and track? Scale creates the first divide, while condition, assembly status, and the type of railway piece determine whether each option suits your collection.
Quick take
The two Micro Trains choices focus on N-scale freight stock, but one is a broader freight-car lot and the other is specifically box cars. The Electric Steam Train Set takes a different route with a locomotive, freight cars, and track, while the Athearn item is a powered HO diesel with a defined road name. Use the price table for the cost spread, then match the product role to your layout plans.

Decision matrix

- Powered HO motive power: HO Athearn Kansas City Southern SD40-2 Powered Diesel Locomotive KCS #678 is the scale-specific locomotive choice, with Kansas City Southern decoration.
- Condition: The two Micro Trains options and the Electric Steam set are identified as new. The Athearn locomotive is used and graded C-5 Good.
- Assembly: The box-car lot, Electric Steam set, and Athearn locomotive are identified as ready to go or pre-built.
Product notes
Micro Trains N Scale Freight Cars Lot Of 6

Micro Trains N Scale Freight Cars Lot Of 6 suits a shopper whose main goal is adding N-gauge rolling stock, not choosing a powered engine. Its new condition and freight-car type keep the role clear, while the lot format gives a single purchase a defined group of cars for a freight-focused collection. The limitation is equally clear: the title identifies freight cars rather than a locomotive or a set that includes track. It also carries the highest listed price in this group, so the choice makes sense when the lot format and N gauge matter more than minimizing the outlay. Pick it for expanding an N freight roster.
4- Micro Trains N Scale Box Cars, New In Box Lot #d

4- Micro Trains N Scale Box Cars, New In Box Lot #d is the focused N-scale choice for someone who wants pre-built box cars with a multicolor design. Its ready-to-go assembly status makes the role straightforward: add defined freight stock without assembly being part of the decision. The limitation is the specific box-car format, which is narrower in description than a general freight-car lot. It is also a rolling-stock purchase rather than a powered train package. The new condition and scale specification make it easy to place within an N-focused collecting plan. Choose it when box cars are the intended addition and a defined, pre-built format matters.
Electric Steam Train Set Freight Cars Railway Track Model Toy Collection

Electric Steam Train Set Freight Cars Railway Track Model Toy Collection takes the package approach. Its included components are a locomotive, freight cars, and track, and the set is identified as pre-built with battery power. That combination gives it a clear reason to choose: it addresses several parts of a train-set purchase in one item rather than concentrating only on rolling stock. The main limitation is the 1:200 scale, which makes it a separate scale choice from the N and HO items. The title also presents it as a model toy collection, so it has a different emphasis from the specifically named railroad pieces. Choose it when the included package is the priority.
HO Athearn Kansas City Southern SD40-2 Powered Diesel Locomotive KCS #678

HO Athearn Kansas City Southern SD40-2 Powered Diesel Locomotive KCS #678 is the direct choice for an HO-scale powered locomotive with a specific road identity. The Kansas City Southern road name, SD40-2 designation, and #678 number give the purchase a clearly defined railroad theme. It is pre-built, with a white shell, red KCS lettering, metal handrails, roof-fan detail, and couplers. The tradeoff is condition: it is used and graded C-5 Good, while the original box has light shelf wear. Choose it when a powered HO diesel with Kansas City Southern decoration matters more than new freight cars or a train-and-track package.
Final recommendation by use case
- For the lowest listed price: Choose the Micro Trains N-scale box-car lot at $30.00 when the goal is a defined, pre-built freight addition.
- For a larger N-scale freight purchase: Choose the Micro Trains freight-car lot at $64.00 when the lot format is more important than the price spread.
- For a locomotive, cars, and track together: Choose the Electric Steam Train Set at $32.20, keeping its 1:200 scale and battery power central to the decision.
- For a powered HO locomotive: Choose the Athearn Kansas City Southern SD40-2 at $61.00 if its road name, HO scale, and used C-5 Good condition fit your collecting plans.
