The LDG are very, very sorry to announce that Class 37 6940 is highly unlikely to work on the 26th. The oil change was performed this morning and the loco was started and fired up fine. All appeared well and a successful test run to Glyndyfrdwy and back threw up no problems. Unfortunately a further check of the new oil showed immediate and obvious water contamination, so we have had to fail the loco to avoid the risk of any damage to the power unit.
The loco does not appear to have lost any water, so we’re hoping the problem has been caused by some residual water in the oil system resulting from the damaged heat exchanger. However, the system was thought to be free of water and until we’ve had a thorough check over that it’s nothing more serious we will obviously not be wasting another batch of new oil or running the power unit.
We’re extremely disappointed to let Folk down, but hope that the debut of 5580, D5310, the Class 104 DMU and 08195 on brakevan shuttles will still attract a few folk along to the Dee Valley tomorrow.
Our sincere apologies for the disappointment.
