These are VERY NICE AND FAST Otis Elevonic 401 Elevators High Rise at the 550 Sherbrooke West Building in Montreal, Quebec, Canada. These Elevators are located in the 20 story wing of this building complex (there is also a 16 story wing that has former Turnbull Elevators) which appears to be a bit newer judging by the inside and the fact the Autotronic panel looked like it had the orange lights, not green for up, red for down, but according to emporis, these were indeed installed and this place was built (both wings) in 1954. These were originally Otis Autotronic Elevators with the Touch Sensitive or Pop Out buttons, but were very nicely modernized in the Early to Mid 1980s (probably 1984) into Otis Series 1 Elevonic 401 Elevators. The motors, fixtures, cabs, controller were all replaced, but they kept the Autotronic panel in the lobby along with the original door operator that makes that classic Otis "door humming sound" that I like!!!! They door track is also original, and these are VERY FAST and THRILLING and FUN TO RIDE, and I love the sound these make when they run!!!!!!! These also run like they were put in today, are in MINT CONDITION, And I love the call buttons!!!! The call buttons look like Dover Impulse call buttons but with Series 1 buttons, and they also almost look like a retrofit on a Touch Sensitive or Lexan call station!!! Overall, these are VERY NICE and AWESOME, and while they obviously aren't original and are modernized, this is still AWESOME because the modernization is at least 30 years old, so the quality still feels very good, the mod is tasteful, and they sure made these fast and fun when they modded them!!!! Anyways, with that all being said, let's GIVE THESE A RIDE!!!!! Installed: 1954 (Otis Autotronic with Touch Sensitive or Pop Out Buttons) Modernized: Early to Mid 1980s (Otis Elevonic 401s with Series 1 fixtures) (Possibly 1984)
