I do not agree, Yes there's a lot of room for improvements. In-cab sounds IMO are pretty acceptable and they support train physics. Some cab sounds are even very good - for example EN 76, ET 22 and EN 57/71. Even Pendolino has pretty okay cab sounds. The problem often is there's not enough variety. For example Armstrong Powerhouse soundsets for Train Simulator provided sometimes up to 20 or even more sound variations to choose from randomly. It really made difference. Especially bad is TRAXX motor sound on certain speeds. It has memorable segments and those start to repeat and repeat until You hate this loco model. Randomly switchable soundsets is a great option which unfortunately is not implemented in SimRail. Another funtamental problem is missing the realistic distance fading effect. The distance when You start to hear approaching train is currently very short. And sounds cut off too early when train passed. I understand developers tried to optimise the game in every aspect but ... now it's the latest time to fix this. All locos and trains are missing outer bogie rolling sounds. Come on! I understand - recordind and editing locomotives/trainsets outer rolling sound is not the easiest job on earth but to leave them completely without is not acceptable at all. In real life there are some sounds which can be heard from kilometers away - horn, coolers, motors, rail joints ... Formulas exist how to calculate fading curve for certain train sounds. I edited lot of soundsets for Train Simulator (Classic) and know how to do it. Sad we don't have any modding options for SimRail. Especially outer sounds need lot more work. In reality - rail joint sounds depend heavily on train speed. Pitch and volume curves have to be edited for that purpose. The lack of wind sound when opening driver windows. New intermodal cargo wagons are too silent compared to other wagons. Rail joint sounds for Dragon locomotives are extremely bad, seems those are not rail joint sounds at all or lack proper editing. TRAXX rail joint sounds are very good for comparison. Rain sounds for all new signalboxes on Grodzisk-Lodz route are wrong ones. Right ones exist but were not choosen for unknown reasons. Please replace them. Those are just some of my thoughts on SimRail sounds. Fixes are coming very slowly.
