An improvement from the GSWR Class 52, the Class 60(GSR D13/D14) was bigger and better and took over main line passenger services until being replaced by Class 305. During GSR days, they were mostly on ex GSWR and DSER branches but were still common on the mainlines. Interestingly No.61 was the only 4-4-0 to receive the CIE Green livery and also the oldest. The following were rebuilt with a Z-type boiler: 60-62, 64, 85-89, 93-96.
