New trolley service to begin May 15, 2022 Havre de GraceNew trolley service to begin May 15, 2022 The HdG’s new trolley service, to be known as “The Tide,” is scheduled to begin service on May 15, 2022. The City is excited to be nearing the end of a lengthy process that started with changing State of Maryland legislation to allow electric trolley use in HdG. After the manufacturer’s very long production back order, we have received the trolleys and will soon finish the after-market upgrades required to carry passengers for commercial purposes on public roads. Please standby for more information as HdG prepares to ride The Tide!
