The slogan “Last Railway in the West Indies” demonstrates its objective to preserve a link to the past, when sugar ruled the island's economy.

[3] The slogan is, however, somewhat misleading, as there are still functional railways elsewhere in the West Indies, in Martinique, Jamaica, the Dominican Republic and, most notably, Cuba.

Hamilton designed and constructed a new type of double-decker carriage, of which the roof may be lifted hydraulically to provide unobstructed open-air seating at the top deck.

[7] These carriages are essentially a miniature full-dome rail car without the vista-dome glass, and with a canvas canopy roof instead.

The lower air-conditioned and carpeted parlour deck has 6 ft (1.8 m) vaulted windows, is furnished with cushioned rattan chairs at inlaid 4-and-2 top tables, and is decorated with paintings by local artists.
