Liberec Tatra T3
Author: dwatry

Here's a video of a Tatra T3 on the Liberec system in the Czech Republic, running on the interurban line to Jablonec nad Nisou, which is temporarily cut back to Vratislavice while the line to Jablonec is being reconstructed.   This is one of the newest T3s on the system, with a low-floor center section.  The newest of these cars were built in 2021 for Liberec and are designated as T3R.SLF.    This shot was taken on the private ROW near Park Nove Vratislavice.    This line was regauged a few years ago from metre gauge to standard gauge, and the few remaining T2 cars being used on this line were retired upon the regauging.

What interesting angled ties (sleepers) on that line. And appear to be metal?

Here's what the manufacturer says about these steel ties (or sleepers in European parlance):

Y-steel sleeper St98 (thyssenkrupp-schulte.de)
Y-steel swell St98 - Engineering at the highest levelSafety and cost-effectiveness even with the most demanding routes: This is what our Y steel sleeper, which has been used in European railway networks for 30 years. Your advantages: increased floor area, optimised stability of the track position and a concise reduction of the threshold requirement and the bedside cross-section.The smaller bedding cross-section, resulting from the geometric shape of this threshold, creates a higher cross-shift resistance and an improved frame stiffness of the track grate compared to the classic superstructure – prerequisites that make conversions possible even without further investments.The preferred areas of application include narrow routes and routes with many constriction points such as bridges, platforms or tunnels, where the specified altitude of the rail top cannot be achieved without complex earth work, tarpaulin spreading or land acquisition.We produce Y steel sleepers for track widths from 750 mm to 1520 mm and different rail types. In addition, we construct special applications such as cog and narrow-gauge railways, multi-rail tracks, auxiliary bridges, guide rails and facilities for catching and management.The range of applications ranges from light mountain railways to full trams according to European standards and heavy-duty railways with 38 t axle load overseas.
