I need help:
Run latest TTDX alpha, however after the appearance of monorail railways could not build any greight trains since the only waggons available were passanger and mail vans

I have also Deutsche Bahn graphix attached.
Here I'm not sure, maybe it's feature,but after 2051 the diesel and ICE3 electric trains start deteriorating quite fast (already 70% for a new train) and no newer models with higher reliability appear. Should it be so? Cause as i remember, in original TTD (or even in first TTD patches) even after 2030 or 2050 there were some 1 or 2 diesel train heads with good reliability still present...
And one more question here: what means monorail/maglev conversion??
Thx & regards.
