Adding a diesel or freight locomotive to your diecast model railroad is more than picking the best-looking engine. You need to match the scale to the track and rolling stock you already own, decide what level of detail matters, and settle on a working style that fits your display. With four new locomotives across three different scales, the decision comes down to which size and feature set makes sense for your collection.
Quick take: If you want a low-priced metal diecast engine with pull-back action, the 7 Inch Freight Locomotive Train North Southern (1/120) is the easiest entry. If you want the largest scale in this group and a classic 1/87 model for adult collectors, the Atlas E 16 07 (1927) gives you a diecast-and-plastic body with rotating wheels. The two other Shing Fat engines sit in the middle of the price range, with the Pacific Line offering a slightly larger 1/94 scale.

Product notes
7 Inch Freight Locomotive Train North Southern 1/120 Scale Diecast Model
At the lowest listed price in this set, this is the most accessible locomotive in the group. The Shing Fat metal body carries a high-gloss red finish with a separate plastic windshield, and the plastic wheels roll freely. The back wheels include pull-back action, so the engine will wind up and roll forward when released. Choose this one if you are starting a 1/120 display or want a working engine without spending much. The trade-off is that 1/120 is the smallest scale here, so it will not line up visually next to the 1/94 Pacific Line or the 1/87 Atlas.
7 Inch Freight Locomotive Train NY - IL 1/120 Scale Diecast Model BLUE - YELLO
This second Shing Fat 1/120 engine costs a little more than the North Southern version, and the NY-IL label differentiates it from the other 1/120 model. It has the same metal construction, clear windshield, free-rolling plastic wheels, and pull-back action. If you want a companion engine for a small freight scene, this gives you a matching body style with a different label. The limitation is that you are not getting a different scale or material; the value is in running two engines together, not in stepping up to a larger format.
7 Inch Diesel Electric Train Locomotive Pacific Line 1/94 Scale Diecast Model
For a slightly larger scale without leaving the 7-inch body length, this Shing Fat engine uses 1/94 and is identified as an FP7 series with EMD as the vehicle make. The silver finish and Pacific Line lettering give it a distinct look from the freight versions. It still has the free-rolling plastic wheels and pull-back action shared across the Shing Fat trio. The trade-off is that 1/94 sits between the other two scales, so it will not match either a 1/120 or a 1/87 layout; you will need to keep it as a standalone display or a separate track.
Atlas E 16 07 (1927) TRAIN 1/87 Diecast Model
The only model here with diecast-and-plastic construction and a 1/87 scale, the Atlas is presented as a good-quality locomotive with rotating wheels. Its dimensions are listed as 187.3mm long, 34.8mm wide, and 44.3mm high to the roof edge. It is marked for ages 17 and up, so it is positioned as an adult collector piece rather than a toy, and the E 16 07 (1927) name gives it a specific prototype identity. Choose it if you want the larger scale and a traditional collector-style display piece. The limitation is that it is the highest-priced locomotive in the group and does not include pull-back action.
Final recommendation by use case
For a low-cost starter locomotive with pull-back action, choose the North Southern 1/120. For a matching pair in 1/120, add the NY-IL version. For a slightly larger scale with FP7/EMD styling, go with the Pacific Line 1/94. For a classic 1/87 adult collector model with diecast-and-plastic construction, the Atlas is the one to pick.
