世界最小自走鐵道模型zz train

"Z" scale is a popular model railroad scale, known for its small size, allowing for more detailed layouts in less space. The "Z" in Z scale stands for "Zeppelin," as the scale was originally designed to fit in the cargo hold of a Zeppelin airship. Z scale models are typically 1:220 scale, which means they are approximately 220 times smaller than their real-life counterparts.

The smallest commercially available self-propelled (locomotive) model train in Z scale would depend on the specific manufacturer and the time of release. Model train companies often strive to create the most detailed and compact models possible, so the title of "smallest" can change with new releases.

As of my knowledge cutoff in mid 2023, one of the smallest Z scale locomotives available was the Rokuhan World's Smallest Model Train Set. This set includes a locomotive and a passenger car that can run on a track with a radius as small as 3 inches (7.62 cm), making it an incredibly compact and detailed model train set. However, it's important to note that the size of the smallest Z scale locomotive can change as manufacturers continue to innovate and produce new models.

For the most up-to-date information on the smallest Z scale model train, it would be best to check with model train enthusiasts, hobby stores, or online communities that specialize in Z scale model railroading. They would have the latest information on the smallest and most detailed models currently available.
