Train 172 (a regional) had operational problems on 4/10. At OSB (and maybe before - I boarded at OSB), 172 could not pull enough power from the overhead wires.

It took about 15-20 minutes until this got fixed (or so I thought) and finally left OSB. ^ But 5 minutes later, the same thing happened!

And 10 minutes later, the same thing happened again!
172 finally arrived at NLC
1 hour after leaving OSB! (It's normally a 20 minute trip.)
Instead of further delays, to Amtrak's credit they found a solution! ^ Just behind 172 was AE 2158. At NLC, all passengers got off 172 and boarded 2158 to continue their trip!
And to make it better - Because of the problems at OSB, they did not have time to collect tickets! And because 2158 does not normally stop at NLC, they knew that all boarding were from 172, so they did not check tickets! Thus, my trip was
FREE!
If I were greedy

, I'd submit my stubs to AGR for credit!
