I suspect you stumbled on some kind of internal form. i.e. for other utilities to purchase rights to run cables on the victrack properties. Or for someone to temporarily rent space. i.e. a building site needs storage for a year while work is completed nearby.

I imagine it's not for normal human use.

I might be missing something here.

These seem to be application forms to lease or purchase land that the belongs to a railway-related organization?

Land that belongs to a railway-related organization isn't necessarily part of a railway. The land could be disused office-space, parking lots, or warehouses.
