Found these at Higashi Mukoshima Station.

Can someone name the green/orange one?

That orange and light-green trainset was part of the old tram system that ran from Tobu Nikko Station west up into the hills and past several tourist destinations in the Nikko area. Alas, that tram system was dismantled many years ago and in many ways, people regret that because bus traffic west of Nikko Station can be really bad at times, especially during Japanese holiday periods.

Ahh have you been into the Tobu Museum? These are placed basically just outside of the museum, probably for promotional purposes.

Really like that limited express, been tempted to get a model but the one's I've seen on yahoo auctions seem to be rather pricey!

Yep. Been to the Museum in 2015.

The Tobu Museum is one of the best small/medium size railway museums in the country, well worth the trip to that part of Tokyo, especially when combined with a visit to the Tobu Asakusa terminal/Sky Tree/Tobu Isezaki Line (aka "Sky Tree Line").  I've been there 3 or 4 times.  Make sure to see the simultaneous departures on the up platform at Hikifune, one stop from Higashi Mukojima.
