About the same time, I decided to replace my old camcorder. My old camcorder was a 8mm tape recorder. For some reason, I did very little train watching with it. Most of that was habit, wanting stills not video. Besides, editing the video was difficult, at the time. A new DVR with recordable DVD, made all the diffference, but a lot of orportunities had passsed. My new camcorder was a mini DVD (still in use, BTW). I set out to play with the two. For trains, it was complicated. First, I would set a tripod and video the train, while taking stills.
More recently, I take video of train, only, with exception. If it moves video it, if it does not move, take a still picture of it.
I do not use the DSLR nor the camcorder for family pictures, but use the cellphone. My last visit with the new camera had one picture on the camcorder.
