i have just picked this forum up and interested to read some of the posts regarding the Bo-Bo Electric to which i have the "Metropolitan" version which i purchased around the same time (2018). To clarify some of the info that was put out about the Destination board "Southbound", from Rickmansworth it would show either of the following " Baker street" or "Liverpool Street" or Aldgate. I was a "Signal Box Boy" at Aldgate Signal Box in 1957 when these loco were still very much part of the running timetable. The train was booked to arrive in Platform 2 at Aldgate where the Loco would "Uncouple" and another Loco from a Shunt spur would couple up to the front end and take the service away. the Loco would then travel up Platform 2 and shunt on to the Short Spur for the next "Arrival"
