TRS22 Retail - PC & Steam (PC & Mac) 12242, 122138 & 121964


TRS22 Retail - PC & Steam (PC & Mac) 122142, 122138 & 121964

We have a new set of Beta builds for you this weekend. Thank you to all those who have currently tested Trainz Plus and TRS22 Beta. We have a series of builds and some will have MPS Support.

*** These builds DO NOT have prebuilt shaders! ***

This will cause the first launching of Trainz Plus/TRS22 will take significantly longer, as will the first viewing of any HD Terrain while the shaders are built on the first run. This is not a bug. Once the shaders have been built, it will no longer need to be rebuilt and Trainz will return to regular loading times.

  • Initial long load times
    • Main Menu
    • First Route loading
  • First HD Baseboards viewed (these will appear white/transparent) for several minutes

As usual, we encourage you to try things out with a fresh install first and then work towards more extensive testing using your unique installed content.

Please report any bugs using this link:

There is an issue with the drivers not changing sides when a train changes direction (AI or Manual), the driver stays in the cab of the first direction travelled at game start. While this doesn't really affect the operation its annoying when selecting the driver from the menu and you end up on the wrong side of the train.
Hi. n3v_laurence, That was a nice piece of information for modern PC grade Trainz.

Where could we get a similiar bit of information for TS3 iPad? The locomotives in TS3 seem to be some from TS2 and the remainder from PC grade units. TS2 had a nice start on collecting numerous locomotives. Some like the UP GETLs Veranda series with a proper fuel tanker and the ATSF RSD-15 in blue pinstripe are from Trains Forge and would be perfect for TS3.

Do we have to hope that Trains Forge or N3V or Pro Train or Jointed Rail or some individual would make these two items available to TS3 use. There are numerous “free” locomotives and cars available from several of these businesses. How can any of these be made available to TS3 train people. I am pretty sure that it is not only kids who play TS3. Many people travel and the price of top end iPADs most likely results in adults using TS3 also.

Thanks for any insight and information that you can provide.
