From the beginning of the seventies and well over 30 years onwards, the Bn / Bns carriages were the backbone of Zealand's regional train traffic.
In the period 1971 to 1983, Scandia in Randers thus delivered no less than 267 Bn wagons, the first 24 were delivered brown-painted, while the rest were delivered red.
In trunks of typically 6-8 wagons, they could be seen almost everywhere on Zealand, pulled / pushed by first MY and MX, from 1977 by MZ, from 1981 by ME, and finally from 1986 also by EA.
Due to the characteristic clapping sound, when the train driver closed the doors of such a trunk, the trains typically went under the designation "clap train".
From approx. 1990, the 217 newest wagons were renovated and modernized, first 100 wagons ("reno II"), and then 117 wagons ("reno III"). The wagons got i.a. built-in closed toilet systems (two different locations of the tanks), and also got new colors on seats and walls.
In step with the introduction of the ER trains in the first half of the nineties, the remaining carriages were scrapped or sold, several carriages thus ended up at various Zealand private railways.
In 2006, after many years of intensive operation, the wagons were ready for retirement, but when, due to problems with the IC4 fleet, they were forced to keep them in operation for a few more years, they became approx. 100 remaining wagons during the first half of 2006 foiled blue.
But in 2010 it was over, on August 13, 2010, the last passenger train ran with Bn equipment, and an era of 39 years was thus over.
Although the Bn wagons belonged to Zealand, they also came west of the Great Belt on various occasions.
IK 82 IC 103 thus consisted of a Bn tribe all the way from Copenhagen to Frederikshavn, where the tribe spent the night before returning to P 588 Frederikshavn-Copenhagen on Sunday.
Even though there was a Bns in the trunk, the trains were pulled both to and from Århus, as at this time there were only quite a few locomotive drivers west of the Great Belt who had a certificate for Bns.
With the opening of the fixed link across the Great Belt in 1997, Bn equipment was used in several weekend trains to and from Aarhus, the 117 carriages that had been through the Reno III program in 1991-1993, were in fact rebuilt and equipped so that they had to drive through the Great Belt Tunnel.

The models

Cast metal chassis and plastic upper. Steps of etched metal, and handrails of metal wire. Detailed undercarriage, with i.a. resilient buffers and imitation brass screw couplings. Interior with i.a. correct seats and detailed painting.
Detailed bogies, and rubber beads at the soft rubber transitions.
Two brown wagons are made in the original version without electric heating, the rest of the wagons are either red or blue and with electric heating.
With the red and blue carriages that are made, tribes can be propagated from three time-typical periods:
• From the mid-seventies, and up through the eighties, when the new red design with Helvetica inscriptions was introduced and the carriages were not yet modernized.
• The nineties and first half of the zeros, where the wagons were still red, but were modernized by several rounds.
• Last half of the zeros, where the wagons were blue and had via inscriptions.
Revision dates on the sides, and painting indications on the gables, are for almost all the produced wagons in accordance with what was actually written on the wagons, as a very extensive private archive of DSB´'s passenger car equipment has been available during the work with the wagons.
Furthermore, extensive documentation material from the renovation program "Reno III" appeared in connection with the work with the wagons. This program included the renovation of 117 Bn wagons at the conversion workshop in Aarhus from September 1991 to June 1993 (the wagons that subsequently received the fixed sub-letter "o", and among other things could be identified by the fact that they were given white boxes around the door handles). This material is also used in the selection of numbers.
The 100 Bn wagons that were through the Reno II program in 1990-1991 received new furniture, and wagons from this program have therefore been omitted in the red version. (These wagons were given the fixed sub-letter "v").

Red, without white door markings, steam heating, i.a. for use in the last MX passenger trains. With interior lighting and tail light, supplied only for DC operation
