Cross the right foot tight to the left, then bring the left over the right and push in the “air” to complete two feet perfectly together. Don’t forget to start this when you see the train but it must be complete before the train meet you at where you stand on the track. If it is not in don’t to order god knows what may happen!
Also try your best to keep breathing calm breaths. You will not actually get hit by the train, and no one will push you. I know how you feel with the horrible images that rush to your mind (as the train high speeds into the station) of your body crushing between tracks and train, are painful and not avoidable. Remember it only lasts a minute and standing far, far back from the yellow line will keep you safe.
