This second post has a link to the video and 6 more photos of the locos seen. At this moment in time I won’t be adding photos of all the units as there were quite a lot of them, but they can be seen in the video.
Link to YouTube video or link to photos for this date in gallery. Link to full list of loco/unit numbers
Photos of locos below, ideal for mobile or tablet. Larger photos, including units in gallery as above.
