I can’t speak for other creators of Trainz content, but research is a big and time consuming part of the creation process. While the internet or www (world wide web) is a tremendous help, it is not the end all. While on some matters there is a totally overwhelming amount of information, on others there is little or no information. While it is true that knowing how to make a proper search for the given sought after item(s) is extremely important, in same cases a determination must be made as to the value or importance of what is desired over that of the time involved. Unfortunately, some things have to be accomplished without all that is desired in the finished product. It is a matter of degree of completeness. Many users will not notice that some rather insufficient item(s) is missing, but other might and you may never heard the end to their suffering over its absence. Balancing on the end of a needle is a frightening and dangerous game. Oh, the joys of content creation.
