Ah the 1970's before the "elf n safety" mafia started to treat us all like children!It used to be not uncommon for buses to leave the (front) door open on a hot summer's day back in the 1970s
I can honestly say that I didn't know this, I just always assumed that the door on 66s was opened for the same reason you'd open a window.The 'cab' doors on class 66's are actually external access doors, as they don't lead directly the cab as such. No 1 cab has a pair of short, narrow corridors that lead into the cab (they run either side of the electronics cubicle) and No 2 end has a transverse gangway arrangement, through the radiator compartment.
There are internal doors at both ends (two at No 1 end, one at the other). Shutting the external doors on a 66 makes absolutely no difference to the ambient noise level in the cab. The doors aren't sealed in any way, shape or form. There is about an inch gap at the bottom for starters! The internal doors do a reasonable job of keeping draughts and noise out though. The main reason they seem to be left open is that they are stiff to operate and a finger trap hazard.
On a class 60 both ends have a transverse gangway and, as the doors to the engine compartment are well sealed, the amount of ambient noise is kept to a minimum. Likewise, leaving the external doors open doesn't really make much of a difference either. I personally tended to close them on a 60, but I just push them closed on a 66.
What could you break door interlock on with the cab door that doesn't have a DRA?Some drivers open their cab door (not necessarily fully open) as an anti-SPAD reminder when standing at signals (particularly ground position lights) which are situated very close to the front of the train, and outside the driver's immediate line of sight. Obviously drivers would not draw up so tight to a signal in normal circumstances but sometimes a train has to be taken out of a siding in which it only just fits, so breaking the door interlock gives the driver en extra level of protection.
All our EMUs lose door interlock if you open the cab door. 313,317,321,365
Interesting for 313s as Merseyrail units don't have interlock on the cab doors.
Ummm...The S stock, and presumably 2009 stock as well, have got sealed interlock switches for the cab doors, so they must remain closed whilst in operation. The 1992TS have got a system whereby if the train is being driven manually, it can have the door open, but if it is operating in ATO, it can't - which is a fair system because you don't want to accidentally send a train off into the tunnel with the driver left on the platform!
Given that they're completely rewiring the train, we'll need to wait and see, depends on if you're referring to the Vivarail units or the RAT units though...The D78 Stock on the District Line can operate this way with the cab door open. I wonder if its still a feature in its new guise?
I've been on units with well over 2kW of cab heating...(!)How warm are the cabs - you'd imagine they'd want some kind of ventilation to keep the drivers on the ball.
Saw a HST pulling out of Paddington last Thursday with the door open, and it was not a warm day.
The off-side cab door on D Stock is permitted to be open with only a driver present, no audible alarm is present. As soon as a second person enters the cab, the door must be closed.There is the issue that having a cab door open on all modern LU stocks requires operating a (normally non-sealed) interlock cut-out switch, but the corporate blind eye applies here too.
S Stock can only operate with the cab door open in 'RM' restricted manual mode at 9mph.The S stock, and presumably 2009 stock as well, have got sealed interlock switches for the cab doors, so they must remain closed whilst in operation.
It was quite common in the breadvan era that drivers had a seperate cab door and they would drive around with that open too.It used to be not uncommon for buses to leave the (front) door open on a hot summer's day back in the 1970s and it's not so long ago they didn't bother with doors at all in London! So I doubt it's particularly dangerous for the driver to have his door open. As long as it is only the driver!
Still a common thing to see sometimes moving around the station at Hull - normally they close them before they go on the main road AND NEVER happens with standing passengersIt used to be not uncommon for buses to leave the (front) door open on a hot summer's day back in the 1970s and it's not so long ago they didn't bother with doors at all in London!

Yeah as do our 317s and Electrostars. I think I misunderstood what RPM meant but now understand it is used in conjunction with the DRA when right up against signals as an extra reminder.All our EMUs lose door interlock if you open the cab door. 313,317,321,365
I'm sure ours have been modified now so that above 6mph you'd get a loss of interlock as well as a brake application!Although 317s only loose interlock-you cloud happily carry on coasting at 100mph with a door open and no brake application.

Ah yes, I did notice yours are not equipped with ADD. Headaches you can just do without when the doors are being pulled as well!They have. The ones on the GN are the only in modified ones left. No ADD indication apart from possible loss of line light and no brake application with loss of interlock.
Mad that they are allowed to run in modified like that.
Evening Standard said:This is the extraordinary moment when a Tube driver was spotted travelling at speed with the door of his cabin wide open at the start of rush hour.
The picture, which was captured by photographer Edmond Terakopian, shows a Central line train moving near North Acton station with no physical barrier between the driver and the tracks just feet below.
Tube bosses today said they were investigating the incident and insisted safety was their number one priority.
Wasn't sure whether this was worth starting a new discussion for, but I noticed that this thread is still open. At first glance it looks like the usual Evening Standard hysteria:
"Mind the doors: Tube driver caught running train with cabin wide open"
Tube drivers don't, but they do have to keep their hand on the deadman's handle, and letting go of it will put the train into emergency braking. It is of course Evening Standard Hysteria - Central Line trains can only have the cab door open when in manual mode (ie with the deadman's handle as a security device), the train won't go in ATO if a cab door is open.I thought that drivers having doors open was reasonably common, especially in summer. I've never considered it to be that dangerous given the driver has to be seated to operate the train.
All of the above (in service) have cab air con, excluding the 67TS...I always used to see the drivers of the older generation trains with their doors open on hot days - mainly the D and 73 stock trains. I don't see what's so wrong with that given the trains probably don't have air con like the S stock does, neither does it have opening windows like the 72/67 stock...
