Just to clarify, RW_Tools uses Serz.exe to uncompress then compress all files which it handles. This includes .bin, .geopcdx and .tgpcdx files.
Due to a limitation in Serz.exe although all the above files open OK, .tgpcdx files which are 2048*2048 pixels and many of the .geopcdx files for locomotives (particularly those produced by RSC) will not re-compress with Serz.exe - This has been the case since the original Rail Simulator when Serz.exe would not recompress the Black 5 .geopcdx file.
Users who do need to re-skin locos with the extra large .tgpcdx files can use the program RSBinTool.exe which is available on uktrainsim.com - This program uses a proprietary serz.dll file written by its author which does not have the size limitations mentioned above (I don't know if it works with the large .geopcdx files, but it certainly will resave the .tgpcdx files)
