The equalizer looks like the MK-900.What about Vekoma MK-900?
The Vekoma MKI'm not sure if there are Coasters that are specifically designed to be just used indoors... A lot of times it is just a Standard Coaster Type that happens to be built indoors. Even Space Mountain is a Bobsled Coaster, kinda like the Matterhorn. Or a Standard Vekoma Coaster for the more modern ones.
