Here are a few preview screenshots of the updates I have been doing to the Milwaukee Road freight cars pack. Some of the original models were quite old and it really showed, especially on the flatcars. These have been rebuilt from ground up, the other cars have received smaller updates too. Additionally, I have moved the three MILW woodchip gondolas from the BN Pack into this one.
This updated add-on pack should be available shortly at Trains and Drivers or, if you already own it, as a free update from your old download link.
