Choosing among model locomotives & rolling stock gets tricky when two candidates serve different jobs: one is a ready-to-go locomotive, while the other is a pre-built set of box cars. The useful decision is whether your railroad needs a locomotive or additional freight stock, then whether the scales and control details line up. Here's the practical split between the MRC Lima PB108 ALCO C420 and the Micro-Trains box cars.
Quick verdict
Choose the JP HO MRC Lima PB108 ALCO C420 L&N Louisville Nashville #1301 DC for an HO locomotive with a light function and analog control. Choose 4- Micro Trains N Scale Box Cars, New In Box Lot #d for a pre-built N scale box-car set. The listed prices are USD 52.31 and USD 30.00, creating a USD 22.31 spread. Because the models fill different roles, the lower price should not outweigh the scale and type you actually need.

Where each product wins
MRC Lima PB108 ALCO C420

The MRC Lima wins when the purchase is centered on a locomotive with a clear railroad theme. Its title includes the ALCO C420 and L&N Louisville Nashville #1301 DC identity, while its details add a light function and painted gray color. Analog control makes the operating setup specific. This is the more direct route for a shopper seeking an HO locomotive rather than more freight cars.
Micro-Trains N Scale Box Cars

Micro-Trains wins when freight cars, rather than a locomotive, are the priority. The box-car type, multicolor design, and transportation theme give the set a clearly defined role in a rolling-stock collection. Its pre-built format keeps the choice focused on adding freight stock instead of selecting an engine. It is the more natural fit for a shopper whose railroad is organized around the N format.
Product notes
MRC Lima PB108 ALCO C420
The MRC Lima PB108 ALCO C420 is a focused choice for a collector who wants the L&N-Louisville and Nashville Railroad-identity attached to a C420 locomotive. The gray painted finish and light function add concrete details to that theme, and the ready-to-go/pre-built status is useful for shoppers who do not want an assembly project. The main limitation is condition: it is marked used, so it is not a match for someone who specifically requires a new model. Select the MRC when the C420 and L&N combination matters more than new condition or a freight-car addition.
Micro-Trains N Scale Box Cars
The Micro-Trains N Scale Box Cars set is the choice for adding ready-to-go freight stock with a clearly defined type. Its new condition, pre-built status, multicolor design, and transportation theme offer concrete reasons to select it, while the box-car designation keeps its purpose distinct from the MRC locomotive. The limitation is role: shoppers seeking a locomotive rather than rolling stock will find the MRC C420 more directly aligned. The two formats also differ in gauge and scale, so the set should be chosen with the rest of the railroad's format in mind. Pick Micro-Trains when new freight cars are the goal; choose the MRC when the C420 and L&N theme are the priority.
Final choice by use case
- Choose the MRC Lima PB108 ALCO C420 when the purchase must be a locomotive and the C420/L&N theme, light function, or HO format is central.
- Choose the Micro-Trains N Scale Box Cars when the need is a pre-built box-car set and the freight-stock role matters more than locomotive features.
- If condition is the deciding tie-breaker, Micro-Trains is marked new, while the MRC is marked used.
These are complementary additions rather than direct substitutes. Match the role and scale first, then let the listed price break a close call.
