The Ertl Train Engines set includes two models from the years 1993 and 2001. These engines are designed at a scale of 2:1993, meaning the 2001 model is twice the size of the 1993 model. This set is perfect for collectors or enthusiasts of model trains, offering a unique addition to any railroad display. The Ertl brand is known for producing high-quality and detailed locomotives, making this set a desirable addition to any train collection. I will be listing lots of train pieces so please check out my store. Thanks
