ADD^▸ (Automatic Dropping Device) is only a protection system that hopefully will safeguard the pantograph
if the wires run out. Once activated the Pan will stay down and can only be reset by a
fitter. The roof strike at Blackfriars is a bit of an anomaly as the 319 would have had to be on DC^▸ (Direct Current) power to get up that severe incline.
    I have seen the procedure on IEP^▸ (Intercity Express Program / Project - replacement for HSTs.) trains for changing from AC^▸ (Alternating Current, or can mean Air Conditioning, depending on context. The second meaning is often used in a railway context and more generally) to Diesil mode. It's a one button job but just relies on the driver's route knowledge and lineside signage.
This sort on mishap will happen from time to time until ERTMS^▸ (European Rail Traffic Management System. A future railway signalling system, with equipment located in the driver's cab, rather than lineside) is up and running. Then the system will prompt the operator and if necessary stop the train if no action is taken.

I'm afraid that little will change until the next control period, unless the Consevitives commit to increased funding of Network Rail. This seems unlikely given the GWML^▸ (Great Western Main Line) electrification fiasco. Also the prospect of TOC^▸ (Train Operating Company)'s sending nearly new rolling stock and BR^▸ (British Rail(ways)) era EMU^▸ (Electric Multiple Unit)'s off lease will do little to ease overcrowding.

Hello there, just to introduce myself. I am a freight driver based in the southeast with
over 30 years experience in the industry. I am an occasional traveller to the West Country and have visited the West Somerset railway a number of times. I look forward to using this forum which was recommended to me by my good friend Broadgauge.
