Unlike general people, Hawaii is not an attractive destination for railway fans like me.
Though railway is not a major transportation in Hawaii, there seems to be a few railways for tourists.
・Oahu Island
Honolulu Rail Transit(Under construction)
Pinapple Express
Monorail at Pearlridge Center
Hawaiian Railway
・Maui Island
Lahaina, Kaanapali and Pacific Railroad
・Hawaii Island
Tram in Hilton waikoloa village
