Nitpicking, nitpicking?
No. *This* is nit picking.

There is a species of elevator sometimes used in colleges for student
transport which does not stop, and does not necessarily ascend vertically
but may traverse, and contains a chain of walk on capsules on an endless belt
onto which one hops.

There were Victorian towns with gas, water, electrical and hydraulic mains.
 Running elevators was a popular hydraulic application: quite smooth and
quiet.
