Well since we are on the subject, I agree with the "no clairvoyance posts" rag. Put something in the title to help us a little.
As for video, I prefer mine horizontal for trains and looking at on my computer. But I don't get my panties in a wad about it. Things change. There is a lot of vertical video shot with a phone whose final destination for viewing is a phone. I'm not sure people realize that most young people look at video almost exclusively on their phones. So we sound like clueless old farts if we get apoplectic about it. I certainly have taken plenty of vertical video of my granddaughter. People are after all, vertical, and movies used to be almost square. 16:9 doesn't lend itself to the close up . Who knows, maybe one day TVs will all be vertical. 
When I was a TV production designer I used a lot of vertical screens for which we had to make vertical content. As soon as plasmas came on the market and we didn't have to use those massive projection TVs, we said "Hey vertical!!' This of course was just background eye candy, but maybe we were ahead of our time.
All that notwithstanding, shoot your trains you post here horizontal.
