It has been confirmed that the original numbers for the Merseyrail Class 777's were numbered from 777701 to 777053. It was originally thought that No 777047 to 053 were going to be the battery fitted ones. My understanding, since then has been amended for the battery fitted ones to be Class 777/1 with No 777040, renumbered to 777140 and the remaining even number ones (upto 052) afterwards to be Class 777/1.
In then meantime, No 20142 / 20189 with assistance of Class 43, No 43468 & 43480 delivered Class 777, No 777012 and 016 to Kirkdale Depot late this afternoon on 6Q77 ex Crewe CS. This leaves five Units remaining at Crewe. Updated location list below:
Kirkdale C.S. = 001, 003, 007, 008, 009, 010, 012, 013, 015, 016, 018, 049 and 140.
Crewe C.S. = 002, 004, 005, 006, and 014.
