I play Simutrans for a very long time now, actually almost from the beginning. But I always used pak64 and I always started somewhere 1930 - 1950.
This week I decided to try pak128 and start in 1900.
In 1900 there are train cars. Some of them are even already obsolete in 1900, but there is no loc in 1900?
How am I supposed to use these cars if no loc is available?
The timeline of pak128 is simply not complete before ~1930. Some content was already created, other content is missing.
However, I have good news for you: The first loco will be available an January 1901
