I think you will find the box say's 'linked' not locked. Its a warning so you don't end up breaking anything as you take it out. To be fair to the member of staff you are referring to, you were in ''Modelzone". Its basically a high street store. They sell a lot more than model railway stuff and the member of staff's interest could be something like radio control cars not trains.

The method of attaching the pony truck has been used before. My old tender drive 8f uses the same method as do my 2 Fowler 2-6-4T's and like my new L1 they do not suffer regular derailments. My L1 runs fine on my code 100 track and points including slips, 3 way points and curved points (all Peco streamline) even at top speed which it will not normally do. For info its R2959 and I did not have to remove any transit pieces. They had been removed by the shop where I bought it because they put all loco's on a short test track for you to see it working before you pay for it.

Yes it works but the problem is that many Bachmann steam outline will not go over them. Anything from derailment to grounding on them can happen.
