- It's a six track train station. SF streetcars stopped out front.
- BayLink rail service to/from the east bay would replace many of
- the buses that use the terminal today.

- Yes, a yard external to the TBT would likely be needed.

-
- Don't worry, they'd fit quite nicely. The TBT is 900 ft. long.
- A CalTrain car is 85-90 ft. long. Since the locomotive does not
- need to be "under the roof", a 10-car CalTrain is okay. The
- longest CalTrain trainsets in regular use today are 6 cars.

-
- Curvature is okay for all standard 85 ft. rail equipment. TRAC and
- TGV are looking into curvature with respect to the extra-long bogies
- under the articulated part of a TGV trainset. In the worst case,
- the TGV equimpment could run push-pull in/out of the TBT (enter &
- leave via the same side).
-

-
- The TBT and bridge were designed for 90 ton cars such as the all-steel
- cars run by the Sacramento Northern. TGV equipment is limited to
- 17 tons per axle and the TGV locos only weigh 67 tons. TGV cars are
- in the 30 ton range.
-
- There is nothing stopping several 40 ton trucks from driving near each
- other on the bridge!
-
- The biggest weight problem is with CalTrain. Cars are about 60 tons
- while the F40s (locomotives) are about 105 tons. CalTrain would need
- locomotives in the 90 ton range in order to access the TBT. Height
- is not a problem either. TRAC believes even Amtrak Superliners would
- fit into the TBT.
-

-
- Right. Questions would have to be answered, but it's considered
- quite possible. Remember that with BayLink, there'd be one track
- per deck of the Bay Bridge. (The tracks of yesteryear were both on
- the bottom deck.) This way, motorists only lose one lane per deck
- while bridge capacity is dramatically increased. Also, it is thought
- that many trips made on BayLink will free up precious space in
- crowded BART trains through the "tube" for people commuting in from
- further out.

-
- There is room for six 900 ft. tracks. That's over 1 mile of track in
- the station... CalTrain would be just fine with 2 tracks, BayLink
- could have 2 or 3 and CalSpeed could have 3 or 2. Also, electrified
- CalTrain and CalSpeed/TGV would likely run off the same 25kV AC wire.
- The BayLink stuff would probably run off typical LRT low(er) voltage
- DC. Both LRT and TGV can be configured to run off dual (or more)
- voltages as current European practice shows.
-
- Yes, and with the above I'm implying that the TBT woudl go back to
- rail-only with a lesser number of buses stopping outside.
-
-

-
- Probably. However, I don't anticipate many people being enthusiastic
- about the last leg of the journey to SF being via ferry boat (as some
- others have suggested).
