CSX has also obtained a few [[EMD F40PH]]-2s that were previously retired from [[Amtrak]], of which are now being used for executive office car service and [[Track geometry car|geometry trains]]. Under CSX, they were originally numbered 9992, 9993, 9998, and 9999, but in 2021, all of these locomotives except for 9999 were renumbered to CSX 1, 2, and 3, and repainted into a [[Heritage unit|heritage scheme]] honoring the former [[Baltimore and Ohio Railroad]].<ref>{{Cite web |date=2021-06-23 |title=New Photo: CSX repaints F40PH locomotive |url=https://www.trains.com/trn/news-reviews/news-wire/new-photo-csx-repaints-f40ph-locomotive/ |access-date=2025-01-30 |website=Trains |language=en-US}}</ref> Another locomotive, ex-[[MARC Train|MARC]] [[EMD GP40-based passenger locomotives#GP40WH-2|GP40WH-2]] no. 9969, was also acquired for the same purposes as the previous locomotives.

With the arrival of [[E. Hunter Harrison|Hunter Harrison]], CSX began to store many locomotives. Following Harrison's death, his replacement James Foote largely continued his policies. The company had over 900 locomotives in storage in January 2018.<ref>{{Cite web |last=Stephens |first=Bill |date=January 17, 2018 |title='There is no turning back' |url=http://trn.trains.com/news/news-wire/2018/01/17-csx-foote-observations-and-look-ahead |archive-url=https://web.archive.org/web/20180120050919/http://trn.trains.com/news/news-wire/2018/01/17-csx-foote-observations-and-look-ahead |archive-date=January 20, 2018 |access-date=January 20, 2018 |website=Trains}}</ref>

CSX ordered ten [[EMD SD70 series#SD70ACe-T4 (2015–present)|SD70ACe-T4s]] in August 2018, which were delivered in July the following year. They are classified as ST70AHs. CSX also has a contract with Wabtec for modernizing their fleet of CW44s. The modernized locomotives, nearly thirty in number as of June 2020, are being classified as [[GE AC4400CW#Rebuilds|CM44AC]].<ref>{{Cite news |last=Landrum |first=Erik |date=2019-07-09 |title=First Progress-built Tier 4 locomotives for CSX arrive |work=Trains |url=https://www.trains.com/trn/news-reviews/news-wire/09-first-progress-built-tier-4-locomotives-for-csx-arrive/ |access-date=2022-03-25}}</ref> In February 2024, CSX and Wabtec reached a new agreement, of which, involves the modernization of over 200 locomotives.

===Heritage units===
In May 2023, CSX unveiled their [[heritage unit]] program, beginning with ES44AH No. 1827 being painted for the [[Baltimore and Ohio Railroad]]. CSX then stated that a total of 21 heritage locomotives would be painted over the coming months, with the locomotive number coinciding with the year the railroad was founded or the name began being used.<ref>{{cite web |last=Bill |first=Stephens |date=12 May 2023 |title=Baltimore & Ohio heritage locomotive is the first of many to come, CSX confirms |url=https://www.trains.com/trn/news-reviews/news-wire/baltimore-ohio-heritage-locomotive-is-the-first-of-many-to-come-csx-confirms/ |website=trains.com |publisher=Trains Magazine |access-date=5 December 2023}}</ref><ref>{{cite news |last1=Franz |first1=Justin |title=CSX Releases Final Heritage Unit — For Now |url=https://railfan.com/csx-releases-final-heritage-unit-for-now/ |access-date=November 21, 2024 |work=[[Railfan & Railroad]] Magazine |publisher=[[White River Productions]] |date=November 20, 2024 |language=en-CA}}</ref>
