He did have it put away while on the train. He made the mistake of taking it out during the train ride to make minor repairs.

Thank you for sharing this image. Shame people stopped looking after the 3rd image. You just showed them with this image that the hand placement when holding a lightsaber isn’t set to a designated area.

You must not have seen many Star Wars movies to know that Luke has held his lightsaber the very same way in the image I took.
