These are more profitable for IR as the rake does not have to be split up into or amalgamated.
It has an advantage of saving on marshalling time, transit time, and scheduling.
Most of IR's freight revenue now comes from such block rakes carrying bulk goods such as coal or cement.
A typical load (full rake) consists of 40 BCN wagons (2200t).

# Parcel trains
Some dedicated parcel trains have been introduced.
Parcel vans are still used a lot for small consignments; these vans are generally attached to passenger trains.
They used to be more numerous in the past but had been diminishing in importance in the 1980s and 1990s as IR focused on larger loads of freight.
High-capacity parcel vans ('Green Parcel Vans') have been used in special-purpose rakes intended for carrying fruits and vegetables.
The high-capacity parcel van carries 23t as opposed to the ordinary parcel van which carries 18t of goods

# Refrigerated parcel Vans
New parcel vans formed by converting old general passenger stock (GS coaches).
These are being used for transporting cars and other automobiles.
Refrigerated parcel van service is available on a few sections.
The coach, manufactured by RCF, has a maximum allowable speed of 130km/h and has a diesel-powered refrigeration unit that can run for 15 days without refuelling.
Services are expected to be introduced on most major routes.
