Neil, I added weight to Windsor Lad and St Gatien as I I found that on the flat they, or any other new Hornby loco drive model wouldn't pull a 14 coach train without slipping. I think I eventually got down to 11 coaches for a Duchess but the older tender drive Brittania had no problem. No the Hornby motors are fine as they are the same that Walthers/LifeLike/P1K use. It's just lack of weight. Most of the Pacfic type Hornby locos I have, A4's, A3's, Duchess, Princess, MN/WC/BoB are roughly of a similar weight that is approximately half the weight of a class 25 diesel from Bachmann and none of the diesels I have have any problems pulling a 14 coach train around. Just as a comparison I still have a few US outline brass locos and a couple of Bachmann heavy mountains with the cast metal boiler. To make the test kind of fair I added weight to the Hornby Gresley coaches I was using based on the NMRA standard, intial car weight +1/2oz for inch of length which brings their weight up to around 7 and a 1/2oz which the Bachmann heavy mountain handled without any problems as did my sole Bachmann 2-6-6-2 which has a plastic boiler but added weight. Needless to say my brass Allegheny which weighs in at 3lbs handled this train with ease although it did slip in the early days with 86 two bay hoppers behind it. Something else I noticed from adding weight to the Hornby Gresleys were that they were a lot more stable on the track and didn't derail whereas it was common for them to come off at least once in standard form. But in weighted form even with Bachmann A1 on the front it only handled 7 coaches while a standard weight Hornby A4 struggles with 5 coaches. My DJH Duke Of Gloucester is a better performer than the Pacifics from Bachmann or Hornby but it is still a little on the light side when compared to 4 axle RTR diesel and although it does handle an 8 coach train with ease it to struggles with a 14 coach train in standard weight. When time permits I'll be adding weight to this model as well. The weight I use comes in the form of either number 4 or number 5 shotgun pellets which come in a 10kg bottle for A$32 from my local gunshop in Toowoomba and held in place with fast set epoxy.

<{POST_SNAPBACK}>Just to add to the above list of issues, some of which I have had too, I eventually got round to getting a rake of coaches for this and it really struggles to go up a minor slope. I have five coaches behind it and it seems to be struggling to get traction on gentle inclines. Does anyone else have this problem?
How did you resolve it?
Is the problem that the Hornby motors are still really weak or is it lack of weight not allowing decent traction?
Normally I'd put a bit of extra weight in it but there was so little room in the loco body in the first place. I had to put the decoder in the tender. I'm a bit concerned that this model is only really fit for display.
