Major Model Railway
Manufacturers
Bachmann
Hornbynow including Humbrol and Airfix (or it would if their website worked)
Pecoincluding Wills, Ratio, Parkside and Modelscene
Woodland ScenicsAll sorts of scenery and landscaping supplies
Oxford RailI’m not sure they should be called a major manufacturer. Given that for some of their products, 3+ years have passed since the announcement and they still aren’t available yet, the company needs to do better.
SuperquickThe line of architectural card kits that “everyone” knows about. Nice kits and easy to put together, but ubiquitous and the treatment of building corners is not ideal
Metcalfe ModelsThe better line of architectural card kits.
ScaleScenesA superb line of architectural card kits. Not for the beginner though, and you need a good colour printer.
Suppliers for Model Railways

Alan GibsonKits and parts for many railways The website is hideous (Wizard sells Alan Gibson items and is easier to read), but the range is enormous. You need to know what you’re doing.
ScalelinkA horrible site to navigate but a wide selection of period items. In particular dates on a number of vehicles and figures that have non-modern clothing. Also frets architectural parts and foliage.
