Thanks guys. Glad you enjoyed. It was a team effort. I had the help of a WMRC member who operated the trains, sound and planned the sequences. I used a DSLR with long lens on a tripod, and an iPhone 6, but ironically the phone took much better video than the DSLR. DSLRs are pretty useless at video because the depth of field is too narrow, aperture is locked once REC is pressed, and AF during video is awful so I had to use MF. Phones are great in low light, AF, but too wide a field of view. Must get a little digicam for future use. Tripod really does help when recording video - doesn't make viewers seasick from camera movement. We only used about 5% of the footage we shot. The main objective was to get one continuous shot of the entire IRM ballast rake passing at platform eye level. A pal who used to be an RTE cameraman, and then went to work on films gave me some great advice years ago about video - avoid panning at all costs, and never zoom during a sequence.
I had hopped to weather the IRM ballast wagons for the video but ran out of time. That's next months project. Anyway we had a fun evening operating trains hauling IRMs truly superb wagons. Two brown plough wagons are now on my future radar.
But the main credit is due to team IRM
