Going too fast could cause damage to vehicles
Potential for injury/death I.e. could get crushed
In train assistance, if a train couples up to you and you have to drive from other than the leading cab with full driving control (I.e. propelling)…. what is the max speed and what would you have to do in that driving cab?
20mph
Temporary Isolate TPWS
What risks are associated with fault finding? (3)
Not getting the line blocked if you need to go outside

5mph max speed (no brake continuity)
Guard to travel in the rear and operate the parking brake in an emergency

If only the Pantograph is damaged…..
1. Can you couple up normally?
2. What must you remember to do before moving away?
If you are then driving from the leading cab with full driving control…..
3. What is the max speed?
- Yes, couple up electrically
- Must ensure you isolate the Pantograph

If the Train Control MCB trips in both cabs, you will need to be assisted. If the assistance comes from the rear and you will be proceeding forwards….. what are your actions?
Couple mechanically and pneumatically (so as not to transfer the problem electrically)
Then…. BIC all of your failed Unit & rotational test
Drive from leading end of the assisting train, remember to Temporary isolate the TPWS, proceed at 5mph max
