A few improvements that I hope DTG do to the ACS-64 and Amfleets are as follows. Please use a bump map on the sides of the ACS-64. In TSW2020 it was perfectly smooth like a mirror. The Amfleets should be a little more shiny and reflective than they were before, and should have some small ripples and dents in them. On the topic of sound. The ACS-64 should have some better traction motor sounds than it did previously, as well as functional blower sounds. The Amfleets need flange squeal and brake grinding sounds that were absent last time. Also, the ACS-64 was underpowered in TSW 2020, and the Amfleets had anchors for brakes, so hopefully this gets resolved. Previously, the Amfleet interiors had some low res textures, most notable on the seats and emergency window handles, which also was spelled incorrectly. One final thing that I hope gets improved upon is the safety systems. Previously, ATC and ACSES didn't work properly. Hopefully DTG takes these into consideration, especially as the only part of the original that they are using are the models.
