J-7 - the other two train brothers are J-4 and J-5. what happened to J-6 ? We need to be told !
J-7 looks a little different to his brothers - his primary colour is grey with some black detailing round the windows. He possess the same two sets of four wheels underneath and hook & hole coupling arrangement that both the other trains do.
TF: turn the train over. Find the robot arms folded up in the middle. Fold the panels they're attached to forward so they're flush with the bodywork in front. Fold the front of the train down into the vacated gap & fold the head up (In TFing all three of the train brothers I've managed to pop all three of their heads off and JRX's head ! - for J-7 I'd pull up a little on the front of the head, then pass a pair of scissors or a screw driver down the back of the neck to lever it up the rest of the way) Remove the panel at the back behind the robot's waist. Turn the robot's waist round. Separate the legs and remove the coupling hook and it's connecting poll. Pull down on the legs to extend the upper legs. Fold the rear wheels down as heel spurs. Pull the feet & heel spurs out about 5mm. Fold the feet up. Straighten the arms. Fold out the sides of the removed panel and fold out the flaps at the end of them. Fold down the handle and insert the coupling hook as a missile. Hold extended in front of the robot as a missile launcher or face on as a shield.
The robot is another tall and thin robot. His head is odd - looks very like that of the Beast Wars character Airazor coloured in bright yellow. His wrists and elbows bend, he has ball jointed shoulders and neck (but the neck is a little limited) Waist turns, there's ball jointed hip and bending knees. Thanks to the heel spurs balance is excellent.
By itself it would be a pretty good toy. As it is the three Train Brothers feel very much like they're the same thing done a little differently.
J-7 is Car Robots Toy C-013 and also features in the JRX Giftset C-015
Rapid Run was sold as a Mega sized toy making it poor value for money as it's essentially a large deluxe toy. Of course by this point the UK had turned it's back on the Mega size class though some of the Bullet Train assortment were later available in the UK as "grey imports" through toy shops.
All three of the Bullet Train team and their combined forms had their names reused for the Universe release of Six Train.
