The line features four of the largest bridges on the suburban network: twin bridges over the Merri Creek, between Clifton Hill and Westgarth station, another on the up side of Darebin station, crossing Darebin Creek, and a wooden trestle bridge across the Diamond Creek just on the up side of Eltham. At 195 m in length, this bridge is allegedly the longest curved wooden trestle bridge in use on a revenue railway in the southern hemisphere, and is the only wooden bridge still in use on a revenue railway in Melbourne.
