The cars closer to us have a box/step looking piece underneath the last and first small windows, whereas the back car does not. Do I win a cookie?!
Take care,

Yep you are right and no you don't win a cookie. There are more differences to spot than that.

If you can spot the error, great.
The car at the back appears to have a blocked in window at the rear and also roof vents.
Partially right, both have blocked in windows, thats where the toilet is. But yeah, recessed vents is one difference, the other one is suppose to have raised vents, but I haven't got that far yet and the doors are different.
Unfortuately, I seem to have the misfortune of not having most of the references I used to hand, so heres a side shot of one of the cars I am modelling:
The above is based on the nearest example (Class 465/2 on the wrong bogies and the above is a Class 466 EMU, the difference is that a Class 465/2 has 4 cars (DMSO - TSO - TSOL - DMSO) and a Class 466 has 2 cars (DMSO - DTSOL) and different bogies.
The above is the only photo of a Class 465/0 or Class 465/1 (the difference is the matter of build dates!) which shows the differences in bodyshells, particulary around the windows (biggest differences). I still got to make the cab, which is going to take err... Aaaaaaaaaaaaages.
The reason for the differences is that when British Rail/Network SouthEast ordered these trains in 1990 or there abouts, the order was split between 2 companies in order to keep the cost down, although they still reportibly cost £1,066,000 a carriage, whereas the more advanced and still in production Electrostar costs something like £750,000 a carriage. (Mk3 derrived trains from 1985 or so cost £660,000 or so, go figure). Around 50 were produced with ABB (Or British Rail Engineering Ltd before ABB - Class 465/0s) of York with a follow on order afterwards (Class 465/1) and another 50 around the same time at Metro-Cammell (Later GEC Alstom) at Washwood Heath, Birmingham. Then later, an order for 46 (IIRC) Class 466s were placed with GEC Alstom, hence the large amount of differences.
