Most ''Keystone Service'' trains consist of five cars – four [[Amfleet]] I coaches plus a [[Budd Metroliner|Metroliner]] [[control car|cab car]] – paired with a [[Siemens ACS-64]] electric locomotive. The service has a single class of service, coach class, configured with 2x2 seating.<ref>{{Cite web |title=Reserved Coach Class Seat |url=https://www.amtrak.com/onboard/onboard-accommodations-for-all-your-needs/seating-accommodations/reserved-coach.html |access-date=April 8, 2018 |website=Amtrak}}</ref>
Trains are unreserved between Harrisburg and Philadelphia and reserved coaches between Philadelphia and New York.<ref>{{Cite web |title=Travel Guide to Train Fares |url=https://www.amtrak.com/planning-booking/tickets-reservations/guide-to-fares.html |access-date=April 8, 2018 |website=Amtrak}}</ref> Unlike most Amtrak routes, no food service is available on ''Keystone Service'' trains.

In the late 2020s and early 2030s, all equipment will be replaced with Amtrak Airo trainsets, the railroad's branding of its combination of [[Siemens Venture]] passenger cars and a [[Siemens Charger]] diesel-electric locomotive.<ref>{{Cite web |date=December 15, 2022 |title=Introducing Our New Trains: Amtrak Airo |url=https://www.amtrak.com/amtrak-airo |access-date=December 15, 2022 |website=Amtrak |language=en}}</ref> The trainsets for the ''Keystone Service'' will have six passenger cars, which will include a food service area and a mix of 2x2 coach class and 2x1 business class seating.<ref name="2022 Asset Line Plan">{{Cite web |title=Amtrak FY 2022–2027 Asset Line Plan |url=https://www.amtrak.com/content/dam/projects/dotcom/english/public/documents/corporate/businessplanning/Amtrak-Service-Asset-Line-Plans-FY22-27.pdf |access-date=April 11, 2022 |website=[[Amtrak]] |page=132}}</ref> The car closest to the locomotive will be a specialized "Auxiliary Power Vehicle" which will include a pantograph to collect power from overhead lines and traction motors in the car and the locomotive.<ref>{{Cite news |last=Worrell |first=Carolina |date=December 19, 2022 |title=First Look: Amtrak Airo |language=en-US |work=Railway Age |url=https://www.railwayage.com/passenger/intercity/first-look-amtrak-airo/ |access-date=December 21, 2022}}</ref>

Before the signal, track, and [[Overhead line|catenary]] upgrades that were completed in October 2006, ''Keystone Service'' trains used [[GE Genesis]] diesel locomotives between Harrisburg and Philadelphia.

On weekdays there are thirteen ''Keystone'' trains and one ''[[Pennsylvanian (train)|Pennsylvanian]]'' train in each direction.

There are eight round-trip trains on both Saturdays and Sundays. All but one, including the ''Pennsylvanian'', make the full trip between Harrisburg and New York. On the majority of the trains, the journey between Harrisburg and New York takes approximately 3 hours and 30 minutes, including 1 hour and 45 minutes to travel between Harrisburg and Philadelphia.
