We, that is Teddyberlin and Alcaron occupy us for quite some time (several years) with Trainz.
We started with the Trainz Railroad Simulator 2004 (TRS04).
In the first time, much was still new and unfamiliar in the program,
but gradually it came well into the matter.
Alcaron then also started after some time to build its own object for Trainz.
In the beginning the objects were small and awkward.
But in the meantime, after much practice and test, the objects have become much better.
Sure, not everything is perfect yet...
but practice makes, you know, the master. :)
Together, we have formed the "Devil Industrial Corporation"
in order to joint publish projects or objects under this name.
