IIRC a 3-car set comprising of two outer motors (e.g. the ones Connex/Metro modified with driver aircon) and a random T car was supposedly going to be preserved but so far nothing's happened. IIRC the original 6-car Elecrail set (295M/282M etc.) was vandalised beyond recognition and/or scrapped, unless it's simply hiding somewhere. I think these two cars (edited for clarification: 80M and 222M) are actually better off in Molong (out of site, out of mind and hopefully away from arsonists) until there is interest flowing again, which may take another 30 or so years.
One random thing that I haven't seen mentioned yet regarding 222M - with some of the M cars in the 220s it looks like someone back in 1980 stuffed up when they were being built. The marker lights on five cars are completely different to the standard build, 222M may even be the only remaining survivor with this non-standard design. 221M, 222M, 223M, 224M and 227M all received this treatment (225M and 226M received the normal style as did 228M through 237M). The standard Hitachi marker lights were identical to the second series Harris ones whereas 222M etc. have the lenses placed flush on the stainless steel panel.
The 220s were being built right in the middle of the conversion from D cars to T cars, so it looks like the marker light housings on those five cars were welded shut before someone noticed they were actually M cars rather than D cars (I guess it didn't help with the panto hiding at the back on these cars as well as VicRail's poor positioning of fleet numbers near the centre doors rather than near the cab), and holes were then drilled through the stainless sheet metal to fit the lights. 222M most likely had its light housings (and possibly desto as well) blanked at the same time 996T (aka 1996T) was having its cab gutted and blanked, as the latter car was pictured right behind it after being converted.
