On a previous post comparing some relatively random locomotives from several countries, a great question was raised about how Kato is 'scaling' its trains given that it produces most of its product for its home market of Japan (where all but the Shinkansens are at 1:150) in addition to some key items for the US and Europe.
So, I thought it would be fun to compare an obvious 1:150 model (I think); the Series 787 Relay Tsubame, and compare this to Kato's European offerings; the Thalys and the Class 66.
The Relay Tsubame comes in at just over 12 feet, according to this wiki entry. I had difficulty getting the height for this model of the TGV used for the Thalys, the closest data I could find may not be quite right for the version of the TGV that Kato used for the Thalys model. The Class 66 data came from here.
