Nice one! You coded the spanish crocodile!
It only has 1 pixel alignment fail in the diagonal views, but it was my fault not to show you a clear allocation scheme for this one, since it was too hard to see:
Take a look at the picture: The top left one is the one as it is coded now. Under it the main visual bugs are marked in green (too sepparate lines and 2*1 extra window) Then, in the center there is an allocation scheme with green lines telling you what part of each of the 2 sprites should fit in the other one. And top right how the final result should be.
the 2 red pixels on the roof of the rear front are part of the pantograph of the next section, as the green lines mark.
So the cabine must have 4 windows 2*2 pixels each.
Otherwise perfect! I was quite amazed to see it
About the cars: We are planning to do a new cargo scheme for the Spain set, so don't mind yet the cargo or mail cars. The scheme is not decided yet, so that will have to wait.
However, if you want to release a test view for it, you can code the car carrier as "goods" and give it a capacity of 100 (50+50)
The same with the tankers there, there are some in the tracking table you can code as oil, goods, food and livestock.
About passenger cars: There will be 3 kind of passenger cars for regular and electrified track: long distance, regional and unit. Unit will be the cars to be attached to MUs, Talgo or AVE trains, so don't bother with that at the moment (I have to draw a generic "unit" sprite for the purchause window)
In the scheme at the top of the tracking table you have in the first row the long distance trains (5 cars except the 1st column, that has 4) and in the second row the regional cars (3 trains)
In the long distance cars, the first one is the dining car, just eyecandy. One every 6 L.D. cars should appear. The second is the normal LD car. The 3rd is the bed-car, another eye candy. There should appear 1 every 4 normal LD cars (the first column doesn't have bed-car) The 4th one is the baggage car (a new cargo I want to insert, don't mind them for now) and the 5th one is the mail car. Long distance cars carry 65 passengers.
For regional services there are not eyecandy liveries, just normal, baggage and mail car for all. Regional cars carry 40 passengers.
The baggage and mail cars are the same (there is not one for LD and other for REG) it carries 50 bags of mail.
I hope it helps, please ask me any questions you might have.
