For a new model idea, how about the pilgrimmage train to knock. This would allow IRM to fit a sound chip to relay the sound of the Rosary being said by the pilgrims on board. So with the GM yoke (or yokes) up the front fitted with a sound chip for the engine (or engines if double headed) and the carraiges fitted with speakers relaying the pilgrims reciting the rosary, it would be an interesting combination.....
