Was travelling between Amsterdam and Brussels a few years ago. Took the train. Stop was Brussels Central. I didn't notice an elevator. Lots of stairs from the platform to the upstairs, a carry on and a bigger bag with me. I'm not even 5' tall. Kinda sweating how to do it, but just as I got to the stairs, a lovely gentleman smiled at me and helped me with my larger bag. Was so very grateful for that bit of kindness - I hope he's had lots of good luck and good karma since!!!
