Eight-wide trains

From Brickwiki

Eight-wide trains are, as the name suggests, LEGO trains that are 160LDU (eight studs or bumps) wide. They are built by many trainheads who see the standard six brick wide LEGO train size as too small and aprototypical. There is light hearted debate amongst AFOLs as to which size is better, which is covered in the article six-wide vs eight-wide.
