I am absolutely delighted with my new Accurascale HYA wagons. I bought packs 1 and 2 of the GBRf version to run with my Hornby Captain Tom. The detail is superb with a huge amount of tampo printing, some of which I need my magnifying glass to read, and puts the Hornby loco to shame. The wagons roll freely and the flashing tail lamp with pack 1 works with button batteries which are easy to obtain and instal, and is switched on and off from the outside via an internal reed switch using a magnetic wand. A big improvement on the system used for the earlier PTA wagons which needed to be opened up to connect or disconnect the battery to switch on or off. I would have bought more of these wagons but the limitations of my small layout means there is only enough space for a limited loop so the locomotive can only run round four wagons.
