The Center for Advanced Skills Training in Law Enforcement, better known as CASTLE, in O'Fallon is finally closing in on completion, and its centerpiece one-mile driving track is expected to open next month. Built on an 87-acre parcel north of I-70, the regional training campus is designed to pull driving, range, SWAT and K-9 training onto a single site that departments say will keep officers closer to home for hands-on practice. Local leaders argue that the consolidation will streamline recurring training and help recruit and retain officers across St. Charles County.
According to FOX 2, the Emergency Vehicle Operations Course, or EVOC, is a full one-mile loop that includes an intersection simulation, skid pad and wet-surface lane and is slated to be ready for use in May. During a recent tour, crews were still finishing pavement and safety barriers while trainers worked out course layouts, and officials told the station that the track will likely be among the first parts of CASTLE to welcome outside agencies for instruction.
What the CASTLE campus includes
Project documents and the city description outline a 200-yard rifle and pistol range, a two-story simunitions house for force-on-force drills, a SWAT training compound with bus and aircraft scenarios, dedicated K-9 spaces and classrooms equipped with virtual-reality training systems, according to the City of O'Fallon. The municipal overview emphasizes that putting classroom, range and driving instruction on one campus is meant to cut the travel time and logistical hassles that have long scattered regional training. Officials also highlight designated areas for drone operations and space to host multi-agency qualification events.
How the rollout is unfolding
Phase one, which delivered the firing range and initial site work, opened with a ribbon-cutting in spring 2025, and subsequent pieces are being finished in sequence. Spectrum News reported on the phase-one launch and noted that the Eastern Missouri Police Academy has approved plans to relocate to CASTLE once later phases are complete. Training calendars already show courses listed at the CASTLE address, according to the Eastern Missouri Police Academy's public schedule, which suggests agencies are starting to lock in continuing-education classes on the new campus, per the Eastern Missouri Police Academy.
Who is running and paying for it
CASTLE is a joint operation between the cities of St. Charles and O'Fallon, structured through intergovernmental agreements approved by the St. Charles council. An ordinance on the city's public record authorizes a service contract and lays out the joint-operation framework, including the technology and scheduling vendors that will support day-to-day functions. The governance model is meant to preserve local control while giving neighboring departments a straightforward way to contract for training space and services.
Why local officials back the plan
City leaders and regional police chiefs have argued that the facility should save money over time by cutting overtime and travel costs associated with sending officers to scattered training locations, and they say it could draw outside agencies and conferences that pump extra dollars into the local economy. The City of O'Fallon's project page lists letters of support from state and regional police associations, and officials contend that a unified, well-documented training footprint will improve the courtroom defensibility of officer training. Those endorsements remain a central talking point as the campus moves toward fuller operation, according to the City of O'Fallon.
What to watch next
With the EVOC track scheduled to open in May, the immediate test is how fast regional departments start using it for joint driving and pursuit-management classes. The latest timeline and on-the-ground details come from FOX 2, while official course listings and continuing-education schedules are posted by the Eastern Missouri Police Academy, which together offer the clearest window into how quickly CASTLE ramps up from construction site to fully booked training hub.
