The mention in another thread that a train driver Instructor will get his or her own cup holder brings about an obvious further question .... What (dual) control facilities will be provided for Instructors on S Stock ? In specific, one of the major failings of many stocks is, there is no form whatsoever of dual control. A train with a trainee at the helm is supposedly under the control of the Instructor, however in practise, should a trainee fail to react promptly or accurately to an Instructors verbal command, the Instructor generally has no means of instantly taking over control of his train. By which I mean adding a bit of extra brake or applying an emergency application and then releasing it ! (A blow from the red handle on old stocks). Timings are critical and any error by a trainee may require instant correction to prevent a safety related error (SPAD, over run etc) I assume a nice comfortable seat will be provided for the Instructor  to rival or at least ergonomically match the drivers seat .. after all, it's the Instructors train. The Instructor needs to have all the necessary access to his safety devices from that seat. Instructors not wishing to be hunched up hovering over some distant means of stopping the train all day with dubious or erratic trainees !! In fact the Instructor needs safety devices / dual control period !  (Some push button you can't reach from the seat and requiring a key reset if touched is not fit for purpose (assuming that ever was it's purpose !) aka D Stock ) |

What (dual) control facilities will be provided for Instructors on S Stock ? None I would guess! In specific, one of the major failings of many stocks is, there is no form whatsoever of dual control. A train with a trainee at the helm is supposedly under the control of the Instructor, however in practise, should a trainee fail to react promptly or accurately to an Instructors verbal command, the Instructor generally has no means of instantly taking over control of his train. By which I mean adding a bit of extra brake or applying an emergency application and then releasing it ! (A blow from the red handle on old stocks). Timings are critical and any error by a trainee may require instant correction to prevent a safety related error (SPAD, over run etc) See above lol! I understand your situation though and would offer the following alternatives: a) The judicious application of a shoe paddle to the offending hand, thus releasing the CTBC and causing an Emergency Application of the brakes. b) Slightly nore seriously - It is often IMHO good experience for the trainee to learn through the uncomfortable process of having to carry out a post incident 'discussion'. I assume a nice comfortable seat will be provided for the Instructor to rival or at least ergonomically match the drivers seat .. after all, it's the Instructors train. *spits coffee over screen* Yeah - right...... The Instructor needs to have all the necessary access to his safety devices from that seat.

There is a bit of a debate raging over this very issue as we speak, so I do not want to go into too much detail publically. Aspect/DD or other staff forthat matter are welcome to PM me or give me a call (PM me for my mobile) to discuss this in more detail.
The Instructor Operator will get an identical seat to the driver, the only difference will be that the adjustment controls will be on the opposite side of the seat to the drivers. This means that both seat adjustments will be on the side furthest away from the 'N' and 'O' doors. The Instructor Operator will also get an area of desk to write on, a task light, and an emergency stop button (no key reset and within the reach envelope). Oh yes, and the cup holder!

The solution is simple. One of brake test buttons once pressed acts as a controllable emergency brake. |

Hopefully the S stock emergency stop button will work in the same way - as soon as you release the button, the brake application is released? I find C stocks more difficult, but I'm getting better at using the red handle to give a bit of extra brake without actually dumping ALL the trainline air! Sometimes I wish I had a button that did the opposite, allowing me to release the brakes when the trainee has got in a muddle and is in danger of stopping somewhere daft. |

Ooo, very impressed even that the I/O has had more than a passing thought, sounds good PRJB ;D The solution is simple. One of brake test buttons once pressed acts as a controllable emergency brake. Indeed so, however that ability is puerly coincidental and unoffical. I was angling for S stock to have something designed especially ! |
