The word is generic of the 1920s, that is the name they put over the bay where the station did the lubrications.
A couple of years ago I posted a picture of a station here in the city of St. Louis where that word is part of the wall over the bay. Station is still open.
The sign might be generic, someone needs to identify the font.
