USA: May 11 saw the unveiling at Newark Penn Station of the first of 26 ALP-45 electro-diesel locomotives ordered by New Jersey Transit nearly three years ago from Bombardier.The dual-mode locos were originally intended to optimise service through the new trans-Hudson tunnels between northern New Jersey and Manhattan then being planned by NJT. Passengers on the non-electrified Pascack Valley, Main and Bergen lines would have been able to reach New York without changing trains. But last autumn New Jersey Governor Chris Christie cancelled the new tunnels, part of the Access to the Region’s Core project. However NJT’s ALP-45s can still be used on the Morris-Essex, Main and North Jersey Coast lines, providing more flexibility and allowing more passengers a one-seat ride to Manhattan Penn Station; about 40% of the NJT system is not electrified. ‘These new locomotives will have the benefit of being quieter, more fuel-efficient and more environmentally-friendly than the locomotives they’ll replace, some of which are 40 years old’, said NJT Executive Director James Weinstein at the Newark ceremony. In diesel mode the new engines comply with the latest federal Tier 3 emissions requirements and incorporate a number of energy-saving features along with faster acceleration. The AC propulsion locos will cost around $310m, with delivery due to be completed by late 2012. Montréal suburban operator AMT has ordered 20 units costing $223m, with an option for 10 more. * On May 11 NJT approved the route for a 1·1 km elevated extension of the Hudson-Bergen light rail line from West Side Avenue across Route 440 to a redevelopment zone along the Hackensack Riverfront.
Vaunix, a leading provider of portable and programmable RF/microwave test devices, has announced the release of the first two in a series of Ethernet controlled Lab Bricks. The two new multiport Lab Brick Digital Attenuators are the 4-port LDA-802Q, and the 8-port LDA 802-8, each operating from 200 MHz to 8 GHz for a variety of L-band, S-band, and C-band applications that require the need for single-shot or repeating attenuation ramps.These solid-state, rugged, yet low-cost 50-ohm step attenuators are bi-directional and offer a high dynamic range of 120 dB. They also feature an impressive, ultra-fine step size of 0.1 dB for ultimate signal attenuation control.These portable and programmable RF/microwave test devices have been designed to suit high-speed MIMO test platforms as they are easily programmed for fixed attenuation or swept attenuation ramps/fading profiles directly from the included Graphical User Interface (GUI). Additional testing applications include Wi-Fi 6E, Wi-Fi, 3G, 4G, 5G, LTE, and DVB systems, and microwave radio simulators.Test technicians wishing to develop their interface, can utilize Vaunix’s included LabVIEW drivers, Windows API DLL files, Linux drivers, macOS SDK examples, and more.The portable, hand-held lab brick units can also be packaged as a single rack unit for ATE stands.Click here for more information.
