Amazon UK has great discounts on 2 recently released LEGO City train sets. LEGO City High-Speed Passenger Train (60051) is discounted 23% to $115 while LEGO City Cargo Train (60052) is discounted 18% to $164. Both are motorized train sets controlled by a remote.
It’s better to import these big sets since the price is much lower than the current US price. Just add either set to your cart and use Amazon’s currency convertor at checkout to see the final price in US dollars. If you buy both, you will save on shipping.
