The June 2008 IRRS journal No 166 has a good article on the MK 2D coaches
showing photos of their arrival in green undercoat and a trial train of two
141s in black and tan with the green mk2s in tow at Clondalkin.
It also shows wonderfull photos of expermental livery that was applied
at Inchicore with a overall red and two cream panals,not to mention a
all over navy blue with silver window frames,and the golden brown with
a white centre where the black went on the final choice.
Another suggestion on show was a Duck egg blue with a off
white panel between the doors.Another photo shows a black
roof and black all the way down to just below the windows where a
thin white stripe meets the golden brown.I persume these photos
were taken in 1972 priar to the rolling out in the super train livery
that was chosen.
