I recently attended a train show in Fullerton California and saw that two EK circus G locos had been changed to allow them to be coupled together.  I run long trains and have 5 of these locos.  They told me that the special couplers to allow this would be out in October of 2007. (They used couplers from another type of G Bachmann loco).  When will these couplers be available as parts?
