Well Arop,
You have done it again. A very interesting concept scenario of Jamaica. I only played it in a Medium level, and did manage to get the Gold by 1925, with more than 4 dozen trains operating. I also would build multiples of the same industry to obtain the necessary LIP goal. Half way thru, I jacked the dividend to its max any time that the economy was beneficial. The goal of the LIP did require laying track to every available industry supply, and then establish my independent demand industry. Usually when a player builds a demand industry, the default will not build to be competitive. My engines were not kept longer than 20 years, unless the economy pervented replacement Although there isn't any steel mills, there is adequate steel at some ports, as well as oil. The only problem I had, was that of the Rocks. There isn't enough Quarries to keep the Furnace supplied. Even though the Furnace was close to the Quarries, there wasn't any profits, although they were close to a "break even' level. A player does have to watch for the "disappearance" of Cattle Ranches, and othere commodities which are to supply the "alcoholic" industries. Seeing that I was able to get the Gold 5 years early, I would make the suggestion of those better Tycoons, to play the scenario in a Hard or Expert.
Thanks again Arop for your talents, time, and imagination.
I am a little partial with this Jamaican scenario, as in the 70s, my Wife and I spent a vacation, basically in the Montego Bay area. Due to the rioting in Kingston at the time, our planned trip across the island to Kingston was cancelled. It would have been interesting, as there are many cities along the line, and people travel with any thing that there are taking to market. Becomes a real zoo, so to speak.
We did take a trip up into the mountains to a alcohol distillery on what was called the Governors Coach. A real fun group, and fun was added, as there had to be "honor" used, as the door fell off its hinges, so some one had to either hold up a blanket or the door.
Our opinion of the people themselves were very rewarding. They all had such 'happy' eyes. A lot of courtesy from all, from adults to the younger children. It was one of the better vacation trips which we enjoyed.

This scenario brings back some very happy moments of my Wife and my life.
