The fundamental limits on train size are engine traction and drawbar strength. Remember that when starting the train, at some point the engine to first car drawbar has the entire mass of the train on it; this turns out to be more of an issue than engine traction. Past a certain size, you get an awful ping noise as a drawbar breaks, and then you have *two* trains. -- Graydon -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
