Once again the limitations of the variable tension CAT appear to have caused more problems

Guys:  Calling the ex-PRR arrangement 'variable tension' as the supposed opposite of constant-tension is as wrong as saying the opposite of antifriction bearings is 'friction bearings'.

The older cat is FIXED tension (the tension is 'engineered in' at adjustment time, and doesn't have the self-adjusting constant tension that the newer setup does).  That doesn't mean the tension doesn't "vary" with temperature, age, and other factors: it does.  But calling the setup 'variable tension' indicates that active varying of the tension is the point of the system, when in fact the varying is an undesired consequence of the fixed adjustment.

Amtrak had a failure of an electric switch MOTOR  south of Boston.  Nothing works all the time but trains have for most part only taken 15 - 30 minute delays with an occasional 1 hour.  Probably with the way that section is designed. ?  But no service disruptions indicates a good design.

 EDIT.   After further review  changed post to read it was a switch failure not a CAT electric switch failure.  Sorry ! ! !

EDIT 2  Amtrak has changed the above notice that it is a downed wire--------------   Guess this poster will give up.

Another problem today.  The following Amtrak bulletin does not say exactly what the problem but maybe someone knows ?

Delays between Wilmington, DE (WIL) and Baltimore, MD (BAL) .  Would guess Amtrak is thankful for the reduced schedule due to the snow storm ?

Trains between Wilmington, DE (WIL) and Baltimore, MD (BAL) are disrupted due to power system issues. Repairs are underway, but delays are expected. Confirm your train's status on Amtrak.com or our mobile apps. Thank you for your patience.

Even New Haven <> BOS CAT can have problems but certainly is less than old PRR especially PHL - WASH.

EDIT  As of 10:30 PM problem exists between NHV - OSB  ( Old saybrook ? )

According to the engineer of train 56 (the Vermonter) that should have left New Haven, a tree came down over the wires which then came down on top of an Acela that was moving from one track to another, and a maintenance vehicle on another of the tracks.  Thus all tracks were blocked.  I was on tr 56 and after an hour delay, a bus bridge to Springfield was set up where the southbound Vermonter was held. 

Judging from what I saw on the arrival/departure board inside the New Haven station, an Acela each way was cancelled.  Based on an Acela sitting next to us on track 4 for more than an hour, I think it was turned to go back to Washington as there were two large boardings in the hour before we got to go inside to wait for buses.  Perhaps there was a similar bus bridge for the Acelas as well as the Boston regionals as well.

That is new wire, and the problems must be related to the recent storm.

CAT too hot today so some slow orders on NEC.  Guess Amtrak just makes it a blanket restriction for even diesel pull trains.

 
 

MARC Service Alert <alert@mtamarylandalerts.com> Amtrak has issued heat-related speed restrictions for parts of the Penn Line. Trains must reduce their speed to 80mph between Washington and New Carrollton and 100mph between New Carrollton and Odenton. Minor delays are possible.

Problem still not cleared at 1650.  Tracking sites show delays even later.  Other web site says it is a signal power problem.  That may still be the 4400 V 100 hZ power.  What is unknown is why has Amtrak not continued the program of getting the standby commercial power setup for signal power along this corridor ? 

 

Train 490 (450 pm Dpt WUS) is cancelled due to signal outages between Washington Union Station, and Bowie State Station. The next train departing WUS will be Train 492 (530 pm Dpt WUS) departing approximately 70-75 minutes late. OptOut: http://mtamarylandalerts.com/u.aspx?336934
