I needed a rear pony for a HD 2-6-4T and immediately went to MTrains as they are on my links page and had been recommended by people commenting on the website. I am very pleased to report that I received excellent service and a well packaged pony truck arrived at a very reasonable price. Only possible improvement is if they took PayPal. I know that this would add 3% to their costs but I think that their prices could rise by this amount without a problem and would add business from outside the UK. The pictures of the spares on the website is definitely an added bonus.
