i would love to bata test it for u plez
Judging from how you act (and the fact that you spelled "BETA" wrong), I doubt you even know what BETA testing is. BETA testing is
NOT for obtaining content early.
It is for helping developers pinpoint bugs that they wouldn't notice because the content would be used in a setting other than that of the developers'.
On a separate note, the R16 definitely needs a new loop sound (as the R38's loop sound is the A/C, something the R16s don't have) along with a bunch of other sound changes that make the train sound like a true WABCO SMEE instead of an train with an RT-2 braking system, Westcode, or an NYAB system.
Next chance you can, see if you can get some sounds off a running R12, R15, R17, R21, or R22 (either the Transit Museum, Shoreline Trolley Museum, or Seashore Trolley Museum)
