railcar
Let an agent explain railcars and their kinds, relay history, technology and notable classes from railway sources, describe postal, parcels and inspection railcars, and distinguish railcars from locomotives, multiple units, trams and railbuses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain railcars and their kinds, relay history, technology and notable classes from railway sources, describe postal, parcels and inspection railcars, and distinguish railcars from locomotives, multiple units, trams and railbuses.
A self-propelled railway vehicle designed to carry passengers, mail or parcels without a separate locomotive, from single diesel and electric railcars and electric rail motor coaches to postal and parcels railcars and inspection vehicles, including classes such as the DB Class 711.1 overhead line inspection railcar, with wheel arrangements such as B B; railcars are used on lightly trafficked lines and as building blocks of multiple units.
What it is for: Carrying passengers or goods under their own power.
It can be explain the vehicle; relay history and technology; describe kinds; distinguish related vehicles.
Distinguishing features
Self-propelled
Single vehicle
Passenger or mail use
Light lines
What it looks like
A single passenger-carrying rail vehicle with its own engine or motors and driving cabs.
Physical character
DB Class 711.1: overhead line inspection vehicle note
wheel arrangement example: B B note - two powered bogies
typical power: 200-600 kW - diesel railcar
How it is recognised
Self-propelled single rail vehicle
Diesel railcar, electric rail motor coach, postal railcar, parcels railcar, inspection railcar, DB Class 711.1
Locomotives haul; multiple units are trainsets; trams run on streets; railbuses are light railcars

What the second pass must settle

- How should railway sources be linked?
- The registry entry has merged aliases including a wheel arrangement and a specific class; should they be split off?
