McLaren Port Huron is host to the annual train display designed and assembled by local physician, Dr. Percy McDonald.

The huge display can be viewed in the South Tower Lobby near the Festival of Trees exhibit.

The trains need time to cool off, so they run at set times:

• 8 to 9 a.m.
• 10 to 11 a.m.
• 12 noon to 2 p.m.
• 3 to 4 p.m.
• 5 to 6 p.m.
• 7 to 9 p.m.

According to McLaren, video and photography are encouraged, and the best results are achieved without a flash. Viewing the trains is completely free.
