The amount of "pressure" used to press the wheels onto the axles does not make sense as the wheels are pressed to a shoulder on the axles. No amount greater force pressing the wheels to that shoulder is going to hold the wheels any tighter to axles. The pressure or press tonnage is import...

A few thoughts... Intermittency doesn't adequately describe the cause of the 2009 Red Line collision. It was a combination of: - Lack of maintenance that led to insulation breakdown on equipment racks in the train control rooms - Incompetent maintenance and incompetent project management that led to...

6050 was returned to Greenbelt last year and the pair was mostly put back together, but as of yet not fully completed.

Maryland will manage Purple Line construction if partnership falls through, state officials say https://www.washingtonpost.com/local/trafficandcommuting/maryland-will-manage-purple-line-construction-if-partnership-falls-through-state-officials-say/2020/08/05/075b9798-d740-11ea-9c3b-dfc394c03988_stor...

Mike- what types of propulsion and HVAC upgrades were they looking to complete? IIRC, Merak did the HVAC for at least the 5k, 6k and now 7k cars. Yet it seems that the 6k was a big upgrade over the 5k. Then Bombardier was contracted for the MITRAC propulsion that the cars had through their lifespan...

All of the 1k, 4k, and 5k cars have been scraped with the exception of 1000 and 1001 (non revenue preservation). A minor point of clarification: 4000-4001 and 5000-5001 were all retained as "heritage fleet" along with 1000-1001. The 5k cars were basket cases from the beginning and remaine...

Conditions will be no different then any of the other 49 surface or elevated stations in the system. The view will still be pretty cool wind screen or no windscreen. That's all well and good for rail fans like us, but ideally the station should be capturing some of the other 25 million annual IAD p...

You are 100% correct, and are asking the $64,000 question that all the local media have failed to. My internal contacts are tight-lipped about this, but I have a (two part) theory about this: a) there are an increasingly large number of bobbing track circuits around the system and there has been for...

I'm curious to understand why this facility would be necessary. Since a policy change in late 2017 requiring cars be serviced only at their "home" shop, the facility at Branch Ave and the massive expanded shop at Brentwood have effectively sat idle. Last year nearly all employees except fo...

Had an interesting experience over the weekend on the Penn Line. Was riding southbound in cab car 7848 near the control stand, there was a loud bell that was intermittently but persistently ringing. A concerned passenger actually approached the control stand, opened the door, and demanded an answer ...

Metro is now programming in announcements for which side the doors open. Minor pedantic clarification, but these are not "programmed" in the sense that they're hard coded, the trains are actually reading the platform ID code from the TWC as they enter the platform limits and generating th...

Found it interesting that WMATA has the freedom to increase their personnel-on-ROW speed from 10 to 15 mph (restricted?) without FTA oversight. Not that it’s an unsafe speed, but that’s the kind of thing that would have been a months-long process had it been a heavy railroad. I always forget how fe...

Twitter users are apparently moronic hypocrites. On one hand they constantly complain about wasteful spending at Metro, but they're going to rejoice that Metro is now going to pay a company to haul away 192 cars that we spent hundreds of millions dollars engineering out all of design flaws over the ...

MARC has only themselves to blame. I don't have any information about this but I would hesitate to jump to conclusions. There are finite resources available to facilitate: design, development, construction, installation, and (the big one!) integration for something as niche as PTC. Given everyone i...
