I've finally released my first grf: "Default set extension".

After year 2051, we have a lot of stations with a lot of platforms to handle the trains. Some stations are fully optimized but cannot handle more trains than needed.
For this case, I've created a new grf which contains only maglev vehicles. The wagons can carry more passengers or cargo than the standard wagons in OpenTTD and are released in year 2060, 2110 and 2160.
Since the wagons can load more passengers and cargo, the train weights are higher and 3 new engines are also added into this grf.
Currently, only all wagons for the Temerate landscape are available in this grf. Other landscape wagons like paper and water are not available.
I would like to have some feedback to improve this grf.
