Although the coasters structure and the adjacent glass structure are physically decoupled, dynamic loads from passing trains induce high frequency acoustic and structural microvibrations in the immediate vicinity. If the glazing support system was engineered for a strictly static environment lacking adequate dampening or the capacity to accommodate bending moments, these sympathetic vibrations will cause critical stress concentrations, leading to material fracture just as what you're seeing in this photo.
If this failure was caused by a localized, external physical impact, remediation requires only a simple panel replacement to resume normal operations. However, if the root cause is vibration induced fatigue(most likely) it indicates a systemic design flaw. Under these conditions, the structural integrity of the entire facade is compromised. The glass retaining supports must be comprehensively redesigned and retrofitted to absorb kinetic energy; otherwise, progressive failure of the remaining panels is highly probable over the structure's lifecycle. This may cause a delay on ride to address the issue unfortunately.
