Some new trains are pulling into Grand Central Terminal for the holidays, although you might have a hard time boarding them.

The 15th annual train show is back on track.

It features tiny replicas of Metro-North and subway trains weaving in and out of a mini Grand Central, and through city blocks.

We spoke with kids of all ages who say it is a holiday staple they and their families flock to every year.

"Every holiday season when the trains are on display, we come and have a look at all of the trains and I think they're fantastic," said one.

"I think it's great for Christmas especially the seasons and I look forward to it every year," said another.

"I like how they go back and forth, the freight trains," said a third. "I like them best."

The train show runs through February.
