KR Models revealed it is developing a ‘OO’ gauge model of the experimental BR Southern Region 4-DD double-deck Electric Multiple Units (EMU) at the 2021 Great Electric Train Show on October 2. Information below is courtesy of Hornby Magazine see here.
Built at Eastleigh Works in 1949, two four-car double-decker EMUs were developed for use on the Southern Region’s Eastern Section. Each was formed with Motor Third Brake vehicles at each end, sandwiching two Trailer Thirds. Designed by O.V.S. Bulleid, they were an experiment to find ways of reducing overcrowding on commuter services to/from London termini such as Charing Cross during the peaks.
Numbered 4001 and 4002, both units featured seating on two levels with a notably different appearance to a standard 4-SUB unit, particularly the bodyside profile with exterior doors and curved windows along the roofline, which added to their cramped appearance. The two four-car units could each seat 552 passengers, compared with 386 in a standard 4-SUB unit.
Whilst their capacity was impressive, their loading capabilities were not as dwell times at stations took longer while passengers boarded and alighted – standard units could stop and restart much quicker. No further units were built, although the two 4-DDs continued in regular use for just over 20 years.
KR Models is planning to release examples of 4001 and 4002 as four-car packs in BR green, BR green with small yellow warning panels and BR blue. Each ‘OO’ gauge unit will feature two powered motor cars, interior illumination, steel buffers and close couplings.

Prices start from £350 for Digital Command Control (DCC) ready units, while DCC fitted and DCC sound-fitted (ESU LokSound V5.0) examples will also be available. An anticipated release date has yet to be confirmed.
Thanks to my friends at the Blood and Custard website the unit history including livery change dates is covered here.
