Steam or Diesel Power

When it comes to modeling locomotives, one of the most important decisions you will make is whether to focus on steam or diesel power. Both types of locomotives have their own unique characteristics and offer different modeling challenges and opportunities. Here are some things to consider when deciding whether to model steam or diesel power:

Steam locomotives were the dominant type of locomotive until the 1950s, and they can provide a lot of nostalgia and historical interest to a layout. However, they are also more complex and require more maintenance than diesel locomotives. Additionally, many steam locomotives are larger in size, which can impact the layout design.

Steam Locomotives:

  • Historical significance: Steam locomotives were once the primary source of power for trains, and they played a significant role in shaping the history of rail transportation. Modeling steam locomotives can provide a sense of nostalgia and historical interest to your layout.
  • More complex: Steam locomotives are more complex than diesel locomotives, with many moving parts that require maintenance and care. Modeling steam locomotives can be more challenging and time-consuming than modeling diesel locomotives.
  • Visual appeal: Steam locomotives are often considered more visually appealing than diesel locomotives, with their distinctive shapes and billowing smoke.


Diesel locomotives became the dominant type of locomotive in the 1950s and continue to be used today. They are generally more reliable and easier to maintain than steam locomotives, and they offer a wide variety of models to choose from. However, some modelers may find them less visually interesting or less historically significant.

Diesel Locomotives:

  • Modern relevance: Diesel locomotives are the primary source of power for trains today, and modeling them can provide a more contemporary and modern feel to your layout.
  • Simpler design: Diesel locomotives have a simpler design than steam locomotives and are generally easier to maintain and operate.
  • Wide range of models: Diesel locomotives come in a wide variety of models and designs, making them an attractive option for modelers who enjoy collecting and modeling different types of locomotives.


Ultimately, the decision to model steam or diesel locomotives comes down to personal preference and the era or location you want to model. Both types of locomotives can provide a unique and rewarding modeling experience, and many modelers choose to incorporate both types into their layouts for added variety.

Regardless of your choice, it’s important to research and choose locomotives and rolling stock that are appropriate for the era and location you’re modeling. This will ensure that your layout is historically accurate and visually appealing.

  1. Or you could model the transition era, post WWII through to the late 50’s, in the US. And let’s not forget the electrification in the Northeast. Build your railroad in the NE Corridor in 1950 and you could build overhead high-voltage wires, and run some cool looking electric locos (I personally love the GG1), along with steam and early diesels.
