Being a greedy git i have three of the SNCF jobs - probably my favourite amongst my fleet. I have to admit I have never been enthralled by the Bachmann-like Heath Robinson hook and loop affair that keeps the two units together. When running heavy trains this always seems the weak link and frequently the parting of ways take place in the most inaccessible places. Has anyone modified (or substituted) this assembly for something more substantial and functional?
