Well, maybe not exactly a “system”.

Here is a very nice review of Maui’s Sugar Cane Train which is a train that uses the railway that was originally built for transporting sugar cane and mill workers back when the sugar cane industry was booming on Maui. Now, this steam engine train offers various excursions. Their website says, “although the canefields are gone, the train will continue to transport visitors between Lahaina and Kaanapali along a scenic journey from the Maui of yesteryear to the beauty and charm of Maui today.”
