Create transects along generalized polyline

I'm using ArcMap 10.8 Desktop

I have a study region encompassed by a polygon (about 100km around - see attached). 

I converted that to a polyline, generalized and densified it to 1km segments (the light blue is the original polygon, the dark blue is the generalized line). If the line is converted to points (Feature Vertices to Points), it yields 129 points, about ~800m apart, which is about right (some fitting/equalizing occurs during Densify, I guess).

I want to generate 1km transects along this generalized line (short segments perpendicular to and spanning the generalized line, occurring at regular intervals - see my hand-drawn red lines), presumably at the vertices.

Any ideas on how to do this?

There seems to be a tool that will do this with a route, but then my question shifts to "How do I convert this line to a route?"

Thanks in advance.

I am still on ArcGIS Desktop 10.8 too and use (paid) ET GeoWizards - Miscellaneous - Create Station Lines
