We have a three car ABe 8/12 Allegra, there are multi pin electrical connectors between carriages. When connected the plugs are held tight and difficult to disconnect. This has been true for all four plugs on these carriages until today, for some reason one plug is now very loose and will not stay connected. I cannot see any damage and there doesn’t seem to be anything missing like a small spring for example. The plug fits perfectly but is very loose fitting, has anyone seen a problem of this sort and is there a fix?
