Finally got round to sorting out the Belgian moves from my BeNeLux Interrail in March, might head back over later in the year so the list may grow! Numbers in italic are units that were in the same train, but I only count the unit that I'm in, so they're just for reference or 'semi-copped'. Here goes:

(For those wondering, yes I did have a game of 'Brussels Bingo' in the evening peak on one day!)
