*** I guess the question is why - its a very rare loco that cannot have a decoder fitted directly in N and I cannot think of one that all that difficult in 4mm scale.... certainly all are less work than trying to add a wagon coupled to the loco convincingly!
BTW - not a good idea to add heatshrink to wire between wagons and loco - even on 4mm scale, it'll stiffen the wire too much, and in N, it'll just not work... Simply use the appropriate sized wire.

<{POST_SNAPBACK}>I have been having some thoughts about leaving locos coupled to say a small van or other wagon. the chip could be placed in the wagon and a small umbilical run between the two. With mini wires and small heat shrink (black) the umbilical could be made to look like a vacuum or airline.
there are mini connectors available which could be sited under the wagon if decoupling was required.
