This remix is the real working OTIS Series 1 (Actually known as a 211 LVM), and it's hydraulic. It's got the "darrow_single_otis" and "darrow_double_otis" parts as well as the proper "Series 1" indicator on the panel. It's got skyscrapersim sounds.
Beginning the awesomeness with this. Credit to @andrew071117 for the starter Credit to @Panbamb and @halfai93294 for the indicators Credit to @bschlipp02 for the motor
