#421 cancelled due to service disruption

[coventry801]

Got a call this morning saying train 421 for tomorrow cancelled for service disruption.
Anyone know what disrupt the train?
_______
Update:
Amtrak CS was very informative and told 50 freight cars piled up 28 miles east of Lordsburg NM.
421 is terminating at San Antonio.
Looks like Amtrak will bus pax from San Antonio to Tucson and then arrange a trainset to continue from TUC to LAX.

Here's what @AmtrakAlerts on Twitter has to say about it:

Sunset Limited/ Texas eagle Train 1/421 which departed New Orleans (NOL)/ Chicago (CHI) on 5/24 and 5/23 will hold in San Antonio (SAS). Transportation will be provided between SAS and Tucson (TUS). Tain 1/421 will operate as normally scheduled between TUS and Los Angeles (LAX).

Sunset Limited/ Texas Eagle Train 2/422 which departed Los Angeles (LAX) on 5/23 will hold at Tucson (TUS). Transportation will be provided for drop-offs only between TUS and San Antonio (SAS). Train 2/422 will then operate as normally scheduled at SAS. Delays expected.

looks like that would be the train back to LAX tomorrow and will spend the night at TUC
