theSonofNoOne You don't say what Level you are, but obviously 800+? Anyway, the general rule of thumb is to use Local slots for Materials and IT for Gold swaps. If you can afford to send your Locals every 3/4 hours to coincide with IT/Contracts that helps, and buying the Special and Vintage wagons will increase the haul from every train. It's a finely gauged balancing act between earning Gold and Materials, buying Locos, Wagons, Slots or Buildings etc. At least in the early stages. Unless you can afford to throw wads of cash at the game and buy Gems! Try to find and join a group whose players will help with Gold and sometimes Mats for lower level players. It took me years to afford those Buildings, long after they became available, not to mention the Long Haul decorations! Just keep plugging away is my advice, and do the Seasonal 4 week contracts as the Buildings and Train Sets there are the most profitable. And if it's Gems you're after then get the basics right - play every day, use the Portal when clicking Gem Trains to earn an extra 3 every time, play the Daily Game, do Contracts, click on TS wall posts etc. etc. And you could buy the 5 Gems Daily for Life offer... it's a pittance to pay for over 1800 Gems per annum.
