well the subject has firmly shifted from the impact at Jamaica to cell phone use and LIRR tests, so I'll add my 2 cents...
I have taken engineer tests for LIRR, CSA, and NJT. I have been told by personnel, transportation, and/or rules department employees of LIRR, NJT, and Amtrak, "our tests are the hardest." Sounds like a training department point of pride... My opinion is that NJT and LIRR are about equal. For Amtrak, I can only speak about PC testing (below).
I think what makes LIRR's tests hard is the unmerciful grading! For example, a PC test might have a 5 point question: draw Divide. So you draw and lable the tracks, signals, switches, and platforms perfectly, BUT forget to put the little arrow indicating which way is east, which means the whole thing is wrong, and there go all 5 points from your score. The company's rationale is that if you forget one little detail on the test, God only knows what you might forget in the field. I disagree, but hey its their railroad. Another exception I take to LIRRs testing (and a reason the tests are so hard for some) is the reliance on memorization. The famous question "What is the difference between 251 and 261" is supposed to be answered by parroting those two rules verbatim. Leave out a word and you're wrong. Have absolutlely no idea what you're talking about, but spell it right, and you're right! And memorizing all those definitions (what are there, around 50?) and then getting 2 or 3 on the test certainly raises your stress, but I'm not sure it makes you a better railroader. It is feasible that an extremely dedicated student who dosent speak English or even use the Arabic alphbet in his daily life could pass an LIRR rules test through memorization! OK I'm kidding about that.
As for PC tests, LIRR, CSA, and NJT do written and verbal, and Amtrak does verbal only. All three of the passenger RRs I was tested on had their share of UNMERCIFUL verbal exams. The written ones were detailed but easy to pass as long as you know your stuff. A three-way tie. The reference in a previous post to open book testing applies to CSA, in my personal experience. They give you a generic test no matter what line you qualify, so by the third time you pretty much know the questions in order. They put you in a room alone with the door shut, after reminding you to bring your timetable and maps, and off you go! The verbal is a rubber stamp, too. I should say, this is as of about 5-6 years ago, maybe things are better now. But it was a joke IMO.
As for cell phones, I am currently working for NJT, and cell phones are not even allowed to be turned on in the engines or operating compartments of MUs or cab cars. The only exception would be for RR business in an emergency. No loss, except I liked using my phone's stopwatch feature for speedometer checks at the measured miles. And of course it takes away a "legitimate communication" option.
So what's going on vis-a-vis the impact at Jamaica, anyway?
