Ah, Dave, I get it! You weaken the midsection of the train to weaken the price [of the ticket, I presume--analogous to buying damaged goods at the store], before getting back in the train as it leaves the station bound for destination #2. Jumping on the midsection should very well weaken it, depending on weight, speed, frequency, etc. [sorry, I never took a course in Strength of Materials, so can't estimate these accurately]. On the other hand, weakening the midsection of the train will probably increase considerably the levels of risk in the journey, so I'm not sure that the reduced ticket price is a prudent trade off.
And we haven't even begun to discuss the consequences of the sulphur levels in the locomotive diesel fuel. All in all, I think that GRNO should proceed via an alternate metaphor, one less likely to run the risk of material failure and collapse.
