Just some thoughts and observations on the DLC Mass Transit items I've used.
Monorail: Runs over roads so it is non-disruptive to city planning. 180 people per train. Cheaper than railroads. Plus those amazingly useful dual purpose stations. I am currently using the dual monorail/bus stations with monorail as a kind of regional transport with buses picking up people in small runs (3 stops on average) to ferry them to the station. I am very pleased with implementation and effect. It looks good and it can fit into any city. I think Monorail brings the most to the game of all the new options.
Cable cars: My favorite addition. Cheap, flexible and efficient. The lines follow the same placement rules as power lines which basically means, everywhere. The stations are nice and small so they can fit in wherever I want. Finally the throughput is great and very cost efficient. I have put cable cars all over my current city (on Prussian Peaks).
Blimps: The mechanics are good. Draw your own paths. Air travel so the only restriction is on placing the platforms. Cost isn't extreme. With the huge advantages the throughput is reasonably low. My problem comes in that the demand for use is too high. I have huge mass transit redundancies in my city. Monorail with buses feeding and cable cars. I shouldn't have huge buildups of people at my blimp platforms but I do and I can't assign enough blimps to the line to keep up. Its not the 500% limit either. Its that I literally have a blimp waiting to land at every platform as one is loading/unloading.
