Neat find. The second is a better size than the first as they should dominate the figures next to them.
Are you going to repaint or leave it as is? Painting is tempting for war colours but if you are representing a civilian train you can get away with it as is.
Re note about figures while shopping - I've carried 28/15/6 before today but normally had troubles digging the 6mm out of the pocket fluff

. Before you ask - never carried a 2mm strip with me...
