Links to Commercial Vendors
These links are to useful brick suppliers with an emphasis on elements useful for trains. Besides the obvious source of The LEGO® Group for bricks, there are several innovative companies and individuals making complementary elements specifically for the train hobby.
The LEGO® Group - the core supplier of our hobby!
Bricklink - the indispensable way to acquire bricks for any project, including those rare, out-of-production elements!
ME Models - a specialist store with custom sets and, most importantly, an alternative supplier of compatible LEGO® track elements (in the near future)
altBricks - a specialist supplier of complementary brick elements. In particular, I like their stunning range of foliage elements available in a wide variety of colours.
Big Ben Bricks LLC - a specialist supplier of train wheels in different sizes and colours
