Hi guys! In this video we build the biggest lego train track layout and use our LEGO MTA Train and our PJ pugapillar MTA train to run the Lego Track layout. This Lego Train track build has mazes and goes all around our house and even outside. The lego mta train must race against PJ pugapillar lego train and try go around the DIY giant lego track layout and mazes and go through the tunnels that we made. This is a custom Lego MTA subway train that we customized and made to look just like a real NYC subway train. We make Lego train crashes, who will crash first Lego MTA Subway train or Lego Pj pugapillar train. These are very long lego track builds that look like a roller coaster. Thanks for watching! Have an awesome day!
