Choosing between model locomotives & rolling stock comes down to what you want the piece to do: serve as a focused display model or fit a control-oriented railroad setup. The Del Prado Union Pacific FP-7 is a static display model with a stand, while the MRC Lima ALCO C420 brings analog control and a light function. Both are pre-built models in used condition, but their formats, railroad identities, and feature sets suit different shoppers.
Quick verdict
Choose the Del Prado when a ready-made display piece, stand, and Union Pacific theme are the priority. Choose the MRC when analog control and a light function matter more. The prices also create a straightforward split: Del Prado is the lower-priced choice, while MRC costs more for its distinct HO locomotive format and control-oriented details.

Where each model wins
- Del Prado wins for a Union Pacific-centered collection. The Union Pacific Railroad roadname gives it a clear railroad identity for a themed display.
- MRC wins for a Louisville & Nashville-focused collection. The L&N Louisville Nashville #1301 designation and gray color make the selected road identity specific.
Product notes
Del Prado Union Pacific FP-7

Del Prado Union Pacific FP-7 makes sense for a shopper building around a yellow Union Pacific piece that is already pre-built. The yellow color and Union Pacific Railroad roadname give the display a specific visual theme, while the N gauge and 1:160 scale identify the format precisely. Its ready-to-go/pre-built status keeps the choice focused on a finished model. The main limitation is that N/1:160 is a different format from HO/1:87, so it is a poor fit when the intended collection is HO. The USD 19.99 price is the lower listed amount, giving this choice a clear price advantage without changing the fact that scale should lead the decision.
MRC Lima ALCO C420

MRC Lima PB108 ALCO C420 L&N Louisville Nashville #1301 suits a shopper who prioritizes a painted, road-specific locomotive and a two-rail setup. The gray color, painted feature, and #1301 identity give it a defined appearance, while the two-rail system is a concrete setup detail. Its ready-to-go/pre-built status means assembly is not the focus. The main limitation is price: USD 52.31 is the higher listed amount in this comparison. The 17 Years & Up age level is also part of its stated positioning, so the choice is better framed around an older enthusiast or collector purchase than a general children's toy.
Final choice by use case
- For shelf-oriented display: Choose the Del Prado Union Pacific FP-7.
- For analog control with a two-rail system: Choose the MRC Lima ALCO C420.
- For the lower listed price: Choose Del Prado.
- For a control-and-lighting feature set: Choose MRC.
The deciding question is therefore less about a universal winner and more about fit. Del Prado is the focused display choice, while MRC is the better match for shoppers prioritizing a control setup and its HO format.
