Basic Train parts

[Philippe Hurbain]

Train Base 6 x 24 with 2 Square Cutouts and 3 Round Holes Each End (etc...)

This part is not yet certified, but it's available on parts tracker
http://www.ldraw.org/cgi-bin/ptdetail.cgi?s=92088

Train Buffer Beam with Sealed Magnets - Type 2

is indeed missing, maybe part 64422 can do the trick in between?

Train Wheel RC Train, Metal Axle

Available as part 57877. Look also at complete bogie shortcut 2878c02

Looks that our ref 57877 is wrong, seems it should be 57051 (http://brickset.com/parts/design-57051). Couls someone confirm?
