Yea the seats are absolute trash. They are a herniated discs worst nightmare. I dont believe NPCUs have dynamic controls. No control car i have seen has a working dynamic brake controller. its difficult to maintain stable variable voltage across many cars, resistance loss etc.

They can but what tends to happen is the dynamic brake throttle does not pause for setup, so it will set a fault in the IO station because it did not get the response it wanted (dynamic brake) it then usually causes some kind of voltage problem, faults out the IO station and the P42 can no longer be...

While I've long been a fan of Boeing, their poor quality control and cheapness on the 737 Max computer systems cost dearly. They use badly out of date and under powered computers, which doesn't help. They cheaped out on sensors (like angle of attack) and on warnings of mismatch between such sensors...

Huge part of it. The biggest problem they have right now is they use the standard 27 pin MU plugs which are normally all analog and use relays. On the siemens engines, its done with a digital IO station that measures voltages. Ive mentioned before, if you get water in the MU plug the computer shows ...

THE SHINEY RED BUTTON. THE BIG CANDY LIKE BUTTON. WILL HE PRESS IT? WHAT WILL HAPPEN????

The Siemens locos all run on Linux software. The original run away throttle problem they had (around the same time 188 crashed) was a problem in the programming that when reached said bug the OS would crash, revert the date to Linus Torvalds birthday and the throttle would get stuck in power until i...

Its a lot of cute stuff but ill tell you what, its not like its space aged. For example, tapping your foot on the acknowledge pedal on the footboard JUST RIGHT yields a nonsense fault that sets off an alarm that says "ACKNOLEDGEER FOOTPEDAL DEFECTIVE". Its because the pedal, and literally ...

The MARC HHPs only had two that got those mods. They still are not reliable and you still barely see them out there. In fact they didnt run a single HHP for 2 years thru covid

You cannot compare the "teething" of the acs 64 and other siemens engines with the GEs. We loved the siemens when i came. It was great. Its gotten worse. The problems with software modifications to account for poor hardware is not working anymore. The HHP-8 was new in early 2000s. They wer...

So maybe the right question should be - why did LIRR buy such junk? I get it; few choices. But I remember hearing early on that LIRR knew how bad these locos were. LIRR was HELL BENT on only buying EMD powered machines. They got what they paid for. They were a huge thorn in the side of SIEMENS and ...

It should be noted that two of Amtrak’s best performing routes (two of the four with over 90% OTP) in terms of OTP use Siemens trains. The trains seem more than capable of running Harrisburg to Philadelphia and Milwaukee to Chicago. Yea two routes that regularly have two locomotives because ONE is ...

The siemens dual mode 3rd rail edition is a pipe dream. They put a bunch of stuff siemens developed into two of the current DMs at LIRR for testing. They ran a test down the main on all 3rd rail to test braking and accel with the new equpment. i have no idea if it is still installed or not. https://...

There is not going to be a Siemens DM loco. Its going to be an ACS and a Charger one on either end of the train or both at the head end. Siemens has provisions for mode change controls in the ALC software and hardware utilizing a pantograph rear unit. The LIRR and MNRR dual mode order is effectively...
