What is a 'steering link' in the context of locomotives? (cliff notes version please)

I am not sure about this but most likely it is referring to the "tie rod" mentioned in the excerptWhat is a 'steering link' in the context of locomotives? (cliff notes version please)
A triangular tie rod assures stable wheel set guidance.
Use of pivot elements and lateral mounting of secondary suspension springs significantly reduces the rotation stiffness of the truck, resulting in considerable reduction of wheel and rail wear.
Thanks, tie rod makes more sense than "steering" to me in a rail context.I am not sure about this but most likely it is referring to the "tie rod" mentioned in the excerpt
Search for the phrase "tie rod" in the following document (PDF) to see the context:
Charger Diesel Electric Passenger Locomotive
I am not seeing a clear explanation as to why more venture cars are not in service.
Because only half the fleet has been delivered. I’m thinking after the laundry list of issues they halted production until the fixes could be made in the factory. Now there’s 20 cars either completed or close to completion that will be delivered soon.I am not seeing a clear explanation as to why more venture cars are not in service.

Would that be rack and pinon or worm roller?I think it's attached to the steering wheel.
As an example, the lead in plumbing problem most likely was on a customer specified and possibly even customer supplied part. Over the years American customers have shown a propensity towards being unable to effectively manage purchase contracts and to some extent suffer from an initial ambiguous specification followed by the "Christmas Tree Ornaments" syndrome leading to all sorts of cost and schedule overruns. The vendors bear some responsibility too by making unrealistically low bids to try to capture the sale, a result of the specific implementation of a "low bid" system used in procurements which causes inadequate expertise on the buyers side to accept absurd bids.yes cars are Siemens build, but lots of vendor items specified by consumer(Amtrak or regional owner) be it seats , steps , bathroom items etc.
These items are not a Siemens warranty but the manufacturer of these items. and unless we have info on such problems its hard to judge
Or the pipe itself. Who knows what the cast of a dozen specified or procured for installation?Where did the lead in the water come from ? Was it the welds in the copper pipes, or the source of the water ?
Again, interior parts. Hard to tell who specified and procured those. None of this happened on the Brightline Cars may give us a hint.Too strong a magnet on the trays, hand rails falling off - this is Home Depot engineering. I couldn't dream this stuff up.
It seems like Siemens hasn't been having problems with the Venture cars on American ROW. Of course, the Ventures are 125 mph max vs. the 160+ mph max for the new Acelas, and for that matter, has anybody actually run any Venture cars on American tracks at 125 mph, except for a few Brightline test runs?It's a European piece of equipment running on an American ROW. Which are completely different, as they found out with the Pans.
Yes. A venture coach ran on the NEC at 125 mph a couple of years ago for testing purposes.It seems like Siemens hasn't been having problems with the Venture cars on American ROW.

And they run at 110 in Michigan.Yes. A venture coach ran on the NEC at 125 mph a couple of years ago for testing purposes.

Wow I can't believe it was 3 years ago it's been taking a long time for Amtrak's new fleet to roll outIt seems like Siemens hasn't been having problems with the Venture cars on American ROW.
