My version of the game won't play them. I used to use a number of bridge stations with low kuid numbers, but my current build of Trainz Plus will not put them in the game or, when it does, they (on good days) don't work as they should, or else (bad days) completely corrupt the game. I am very puzzled as to why such a huge number of such assets are still in DLS.
Operator error of some sort and/or misunderstanding.
"Kuid35000" is author "jorma0" who has nothing on the DLS, nor does being less than "35000" cause and issue multiple authors with kuid's lower than that are still pumping out content.
I have build 123794 with 29,662 non-faulty and non-DLS (including multiple payware kuids) that are build 3.5 or lower.
