Sorry about delay in replying BosKo, I'd hoped that someone with photos might have come in. The only photo that I can find at the moment is a rather poor b&w one in the October 1970 IRRS Journal - page 254 - showing the summer set at Connolly. The same article has other pictures of the set but these don't show the full train. The summer set consisted of seven of the eight carriages bought by NIR for the Enterprise: locomotive; first 801; grill/bar 547; standards 821, 822, 823, 824; and driving trailer brake standard 811 or 812; locomotive. The second driving trailer brake standard was spare. The winter set consisted of five coaches (two of the standards 821-4 being omitted) and a single locomotive, which if I remember correctly was at the Dublin end of the set.
