I think the railway scene was pretty good , Some people will always find something to be offended about , unfortunately its the way of the world.
My Grandfather served in the War , he watched war movies , and was not offended by any airfix models I built , He did not like the Japanese , Germans, French , Americans , Come to think about it he did not like most nations but would always be very polite to my Cousins Japanese Girlfriend at the time, in fact it was us who panicked when we took her to see a local church in Cheshire and they Had VJ poster in the hallway , see saw them and was understood totally.
One film in particular "Wgere eagles Dare" or was it the eagles have Landed ? anyway He actually felt sorry for the Germans in that and smiled when Larry Hagman got shot..
