  JVR J-type bogie - possibly the simplest form of fully compensated bogie. The central structure is flexible, with outer parts hung onto the centre of bogie sides with clearance allowed for movement.

Still to add - centre pivot and spring,

Typical construction of a single 1st class compartment. In practice these are usually in groups with continuous side panels and droplight panels.

Note that the compartment partitions normally have roof racks on both sides (obviously excluding the end partitions).

Typical 3rd class compartment construction  - similar to 1st class but no seat rests.

Typical construction of a brake 3rd coach

Typical roof construction. The top panel is wrapped around the formers and glued together. The cantrails are added, the cornice/gutter strips are folded and glued in place below the cantrails. The bits projecting down from the cornice hold the coach sides in place.

The roof is removable - held down at each end by a screw.

Still to add - the LED lighting in each compartment, the ventilators and rainstrips.

Typical construction of a composite coach - made up of the above two types of compartment but with continuous floor & side panels. Note the droplights are in groups of  1st & 3rd compartments.

Still to follow - external side structure, underframes and variations for brake coaches,
