The excursion is scheduled to depart Summerville at approximately 2:45 p.m.

Motorists should be aware that the railroad crossings on East Washington Street and East First Avenue will be closed while the train is in Summerville. Drivers should expect delays and plan to use alternate routes during the closure.
