What the heck just went by my house on the railway?

Just now I went to collect eggs since I have been gone all day and on my way out of the coop I see these really bright lights on the railway. Now my house is right next to the railroad tracks in the middle of the country so I'm used to seeing all kinds of strange rail cars. I even see the Barnum and Bailey train go through a couple times a year. I have never in my life seen a group of cars like this group.

Even from far away of it was very bright and as it got closer I could see that the whole car was lit up and not just the front lights like normal. Every car had at least 20 lights on it , top and bottom and everything in between. It went really slow along the tracks and there were about 8 or so cars. The first was the engine pulling it then came a tanker that looked like it was covered in snow or bubbles or something that kept flying off of it from the top and I could not tell what the rest of the cars were except to say that none of them were more tankers.

Can someone tell me what kind of train this is? I won't tell you my idea of what I think it is but I would love to hear maybe from someone who has worked on the railway and can tell me for sure. It was definitely diffrent from everything I have seen.

 

I wish I knew. When I told my brother about it he asked me what I had been smoking but my dad was with me too and he saw it. He grew up in this house and in all of 50 something years he has never seen anything like it.
