Technical challenges of modernization
In March 2017, HITACHI Rail STS rolled out the interlocking management system of the Gare de Lyon in Paris as part of a renovation project commissioned by the French national rail company SNCF. The system, supported by a single safety platform, commands 170 switches, 115 light signals and 800 routes at any time and simultaneously, and thus requires a secure, reliable platform.

In 2018, facing the problem of obsolete equipment and the need for ever greater computing power, HITACHI Rail STS decided to further modernize its safety platform with the ambitious goal of developing a single platform that is also compatible with the constraints of rolling stock and ground signalling.

The first targets were the renovation of the metro lines in the city of Brussels with a Communication Based Train Control (CBTC) system, and the renovation of the interlocking systems of the first 280 mile-long high-speed rail line in France between Paris and Lyon.

HITACHI Rail STS identified 2 key areas of focus in order to achieve its goal:

  1. Conduct logic synthesis on the 68K CPU in order to house the “voter” function of the CSD in the Processing System part of this component, thus making it possible to reuse the coded monoprocessor production chain of the existing voter software,

  2. Port the existing application software, developed in Ada 95, to

Advisors use technology to help clients adjust to the new environment

The Covid-19 pandemic has pushed more financial advisors to figure out how to meet virtually with clients.

Advisory firms have had to find ways to be able to adapt through the use of virtual technologies to keep their meetings going with clients. That newfound comfort will probably change advisory practices well into the future.

To that point, the first Zoom video meeting that the advisors at Salem Investment Counselors had earlier this year to discuss financial markets was not a resounding success.

“We spent half the time troubleshooting people’s connections, and then it shut down after a half-hour,” said Kip Keener, chief compliance officer for the Winston-Salem, North Carolina-based firm. Salem was ranked No. 1 on CNBC’s FA 100 ranking this year.

Keener immediately switched to a corporate Zoom account and says that videoconferencing between employees and with clients has quickly become an integral part of the firm’s operations.

I’ve been amazed at how quickly employees and clients have adapted to this changed environment.

“Historically we’ve been pretty low-tech in how we communicate with clients, and the pandemic really disrupted our communication chain,” Keener said. “I think everyone realized that this was something we had to embrace and between the Zoom calls, lots of emails and phone calls, we’ve been able to roll along pretty normally.”

The coronavirus pandemic and all the disruptions resulting from community and office shutdowns have highlighted the increasingly crucial role that technology plays in financial advisory firms. Not only has technology enabled employees to work remotely when their offices are closed to them, but it has helped advisors communicate more often and more intimately with clients in a period of very high anxiety.

“I’ve been amazed at how quickly employees and
