|If you are...||Make your Advance call...|
|Underway going eastbound (up river)||At the Carquinez Bridge|
|Underway going westbound (down river)||Somewhere between New York Point and MOT Concord (former NWS) Pier 3óCCR 3|
|Moored between New York Point and the Carquinez Bridge||Before getting underway|
At this point you should carefully consider your situation. If you are able and willing to accommodate the bridge tenderís request to delay your lift request time, you should advise the bridge tender of your new expected lift request time (refer to the protocol for precise verbiage). If you are uncomfortable modifying your plans, you are under no obligation to do so. In the end, it is critical that the Advance Call process ends with a firm understanding between vessel and bridge as to precisely what time the bridge will be expected to start lifting. With this firm understanding, you should experience no delays when you make your Lift Request call.
Longer answer: Consider the scenario in Question 2. In your Advance Call you gave the lift tender information that you would be calling for a lift at 1335. He asked if you could delay your request until 1340 to allow a passenger train to pass. For the purpose of this explanation, letís assume you agreed to delay your lift request time until 1340. The lift tender is not expecting your Lift Request call until 1340. If you make your Lift Request call at 1340 the lift tender should immediately engage the lift. There should be absolutely no obstructions.
Once you have given the bridge tender your lift request time, the bridge tender begins coordinating railroad traffic based on this information. If, for example, you told the bridge tender to expect a lift request call at 1340, the bridge tender may have had to hold trains in position away from the bridge to meet your needs. If the bridge tender is left holding trains in position, and your lift request call never comes, the railroad could incur costly delays and passengers may not reach their destination on time. Similarly, if your plans change and your lift request time is pushed into the future (perhaps your speed was slower than you expected), you should immediately advise the bridge tender and update your expected lift request time.
