Talking Thomas and Sodor Island Set

I understand that tender driven trains are sometimes necessary option for special models like this one. Still, powered tenders, trucks, wagons, coaches etc. are just... not the way I like it. Locomotives should have "the power", and they shouldn't be pushed - they should pull the train, even the model train. (I still don't understand why Plarail Emily couldn't be powered.) "Powered tender" always sounded slightly heretical to me.
