Kansai Enkou 45 92 Link -

Alternatively, "Kansai Enkō" might be the name of the train itself, and the numbers indicate the model. For example, some trains have model numbers like 6030 series or 223 series. However, using 45 and 92 doesn't fit typical model numbering. Maybe it's a combination of two lines: 45 and 92? Or perhaps they refer to a specific route or fare zone.
