The Blue Caboose, a family-friendly, train-themed restaurant at 8420 Brookfield Ave. in Brookfield, officially opened its doors on Sunday after three months of work to renovate the space.

By the time his head finally hit the pillow Sunday night, owner Michael Naughton had been working nonstop for about 31 hours to ensure his grand opening was a success.

“It was a little overwhelming,” said Naughton, who estimated that the restaurant served between 250 and 300 people on its opening day. “We definitely sold a lot.”

Naughton originally hoped to open in mid-August, but it took a little longer than expected to finish the dining room, which features a counter where customers’ food arrives via model trains. Most of the work was completed by Naughton’s general contractor, Jason Spaargaren, and Robert Ciszek.

The construction crew is still working to build out the back dining room, which will principally be used for private parties.

After the first day, Naughton said hamburgers were looking like the restaurant’s niche dish. The Blue Caboose served up more than 80 burgers on Sunday.

Naughton also thanked the Brookfield Chamber of Commerce, especially Amy Weinert of First National Bank of Brookfield.

“She’s been a complete resource,” said Naughton. “She was my connection to Brookfield.”

He also had special thanks for his grandmother, Dorothy Kealy, who was instrumental in helping make the restaurant a reality, said Naughton.

The Blue Caboose is open Tuesday through Sunday from 11 a.m. to 8 p.m.
