There used to be sound problems with TRS04, but all problems disappeared overnight when TRS06 came out and TRS04 assumed a saintly mantle.
To be fair I think it is generally agreed that TRS04 sounds are the best out of all the Trainz versions, but Trainz Classics 3 'promises' improvements. We shall see.
For Auran mainly, but feel free to comment, after all you readers are why Auran exist!
So I wasted my money on Trainz 2006? Thanks Auran stitched up again!
But hey...what if TC3 isn't any better{Again}, We are each £20-£30 out of pocket, its just not acceptable, we are your customers.
I've spent the best part of £200 on my whole trainz set up, including third party content,and all version releases, as well as the numerous patches every other blo^dy month, and if a patch or upgrade falls on the start of a new year, Hey here's an idea Auran (Sarcasm iminent) re-box the patch, chuck in a new bit of content and label it Trainz Classics IV!.
This really needs sorting, I'm starting to edge away again.
The only real thing I like about trainz is the surveyor, but when another program comes out which can rival this, I'm going to move I think, theres just too much dissapointment with every release since day one.
I can't say how mad I am but a list of issues that keep rearing their ugly heads on the forums are, (Not in order of any kind)
1. False engine Sounds either gp38 or a quiet BR Class 37 or go away, Nil track clickety clack, No rumbling, flange squeal, Cr£p horn tones.
2. Unreal cab sound/view, control lever sync-sound, very slow brake release/application., cartoonish appearance.
3. Cmp crashing, downloading content which doesnt work with older versions.
4. File innacessability, stupid Kuid system.
5. Re-Dressed surveyor, I.e I looked for a different looking tree under the German scenery tab, I Can't speak German let alone pronounce the stuff Couldn't find it under the English version release so it now takes me twice as long to find an effing tree!, .Surveyour labelling all without Logic, Ie Tside level crossing instead of Level crossing?
Cant do water at different heights, can't put a tunnel through certain angles, track bends awkwardly in opposite direction. Displacement settings not clear...Blah blah etc....Cant lay ballast properly due to a massive circle thingy, Use a set of brushes like in Microsoft Paint....
6. Unreal Train physics, Background sound drowned out by loco horns 2 miles away! Noise dropout, Quiet external noise in relation to a thrashing class 50 that sounds like a mouses fart on external view.
7. Terminoligy lesson #1, Britain invented the train and railways ergo our great empire terminology should be in place.
Turnout= Having a Cr*p LOL!
De-couple=Uncouple
Engineer=Driver
Track gang=Track maintenance crew
etc....
7. Lots more can't be bothered to list, at the mo, im going to look at the NEW train simulators (At least they can spell it!)
I think I wont buy any more Trainz products :'( for about ten years, they will either have sorted it

or be bankrupt by their own fault.
WELL P`$&ed Off!!
