Very nice escalators. I didn't think O&K even existed in Japan until now. The RT-HDLS type is quite uncommon, and being it was built in 1995, it was probably one of the last of it's type to be built. They were replaced by the RTV-HD type shortly after. In the UK and Europe, the RT-HDLS type was mainly installed in Airports and large train/metro stations. Also interestingly this set appear to have been built in O&K's US factory.
