Thanks to peter1138 and his incredible work
, since revision 12924 you can now have a total of 65535 type of vehicles to choose to build..
For NewGRF Developers and Coders
What does this mean?
It means theres no longer the NewGRF limit of 11 ships, 41 Planes and helicopters, 88 Road vehicles and 116 Trains+Wagons..
You can now have for example 10000 ships, 10000 planes, 10000 Road Vehicles + Trams and 10000 Rail Engines + Rail Wagons to choose from to build..
It's now up to NewGRF coders to decide how many they want to have in game and no longer they have the problem of reaching the limit easily..
According to peter, coders can just assign more vehicle IDs in their set or they can of course split the set if they want...
So for easy understanding this means you can have a single NewGRF file with for example 500 Rail Engines + Rail Wagons, you just have to just assign more vehicle IDs...

For Players wanting to have multiple sets of vehicles available to build at the same time
In Patches Menu if you activate in the tab Vehicles the option " Enable multiple NewGRF engine sets " you can have all the vehicles set's you want at the same time to choose and play with..
For example you can load Planeset and AV8 at the same time with no problems and all the planes and helicopters will be available to build..
Another example is UKRS and US Train Set, all the Trains and Wagons from this 2 sets will be available to build..
You can have more than 2 set's at the same, and it doesn't matter if they are planes, trains, ships or road vehicles..
Hey I have right now 5 Train + Wagons sets loaded, 2 planes sets loaded and 3 road vehicles sets loaded
Now go and load many vehicles sets at the same time and enjoy it
Also here is a GRF that will also allow original vehicles to appear even with multiple NewGRF sets loaded.
