Something becoming increasingly noticeable during my time with loco hauled stock on UK routes, is the overbearing sound of the trailing load when in or looking directly at the drivers cab. Ive watched footage of driver cab rides with similar stock ie intermodal on 66 vs GWE intermodal. Whilst Im sure the is a sense of weight and maybe a rumble from behind. The engine would surely take priority, and not the clattering bogies. When compared to TSXX the issue isnt apparent, and it cant even be a TSW game issue, as when running German freight on MSB, RRO and RSN the sound balance is similar to TSxx and the real life cab rides. Its also noticed from an outside camera seeing an oncoming train, ie a pair of 31s with cement. The engines start to fade in nicely then the view is immediately hit with a wall of PCA sound, that spoils the experience. This wouldn't be such a big deal if only watching a pass externally, but the loudness of the trailing load comes through to the cab when driving. My take on it is that the engine, coach wagon sound balance needs to be tweaked.
