All non-toyland sounds are done.
Today the third release of OpenSFX: the sound replacement project or what OpenGFX is for graphics OpenSFX is for sounds.
It can be downloaded from http://bundles.openttdcoop.org/opensfx/releases/
It currently replaces 59 of 73 samples (81%), which means only 14 toyland sounds have to be found/created. After that there's still lots of tweaking to do.
