For sale is this British Rail tank locomotive by Bachmann of Hong Kong - appears to work well in testing and it has Kadee style couplers and does not have a box (analogue system). It includes a British Rail more modern Hornby freight wagon also with Kadee couplers and complete with its box (but I can't seem to find the model number?). Either way an interesting addition to your train set at a very reasonable price.
NB an Ebay member has alerted me to the fact that this is actually an American tank engine: Plymouth MDT 0-6-0, a USA shunter not British.
All works well; postage with tracking will be FREE to any destination served by Australia Post. Thanks for looking.
