Hi,
I have worked on my hungarian Stadler FLIRT and have made little changes. The main change was made by the coupling, two of this EMU can be connected with magnets. It was hard to make the connection without changing or losing the design made before, but I did it. Other changes I made are on the roof. There were some bricks on the roof, but this time I tried to build all things similar to the real one using a photo. And finally I built in the third headlight, and it's able to be filled out with PF led light.
And photos of the updated EMU.
This photo shows the EMU's roof design.
Front view, the third headlight is new.
The whole train.

And an another whole train picture.
Finally the coupling of two FLIRTs. Unfortunately it's only two half, but it was enough for running tests.
