Class LAG 59-60 / BR 98.73 (Locobase 5813)
Data from Christian Lindecke's [] (visited 12 Dec 2003), supplemented by [] . Lindecke offers no commentary on this class. Expanded in every respect from the earlier LAG 0-6-2T (Locobase 5812), this is a virtually identical cross-compound version of the D X local-traffic tanks delivered to the K.Bay.Sts.B.
