Traditional O-gaugers might be interested to see that pressed-steel crossties ("sleepers") were used on some railways in other countries. The photos show examples on standard gauge tracks in NSW Australia in 2008. These are secondary tracks, not currently mainline tracks. I suspect the steel sleepers are not as suitable or cost effective for modern heavy traffic with higher axle loads. [edit: new designs of steel crossties have advantages for many modern applications] 

The first photo shows old style pressed steel crossties in the siding track at right, next to an active main line. They have a boxy rectangular shape.

The second photo shows a steel sleeper with more rounded contours and Pandrol tie clips, in former mainline track near Thirlmere which sees occasional traffic to the state rail museum.

In the third photo, on a currently disused line south of Thirlmere, a steel sleeper is stamped "Colville Ltd 1952". This was former mainline track, bypassed by a better alignment.

Steel ties were used in areas where suitable timber supplies were distant, and/or where materials were vulnerable to deterioration from humid climate and termites. In some places old rails were commonly used for telephone poles along the tracks, for the same reasons.

I remember seeing steel ties on the long-since-defunct 42"-gauge North Australia Railway near Darwin in 1970, but I don't have photos of that.

According to a Rail Safety Investigation report on steel sleepers, (referred to as ties in the US) prepared by the Australian Office Of Transport Safety Investigations in New South Wales, the disadvantages of steel sleepers are due to the inverted trough shape under the sleeper, which makes it harder to pack ballast under the tie (inside the trough) making the sleeper prone to not being able to support the entire axle load evenly.

Also I read on another website that the inverted trough shape on the causes a pumping / suction action during rains. So instead of the water draining through the ballast, it gets sucked back repeatedly after each set of wheels pass over the steel sleeper, eventually making the ballast or the ground under it porous, making the track uneven or incapable of bearing the required axle loads.

I have to admit that I am not a Civil Engineer & I came across these information in the past when I wanted to know why steel sleepers where not popular in the US since I remember seeing them being used at many places in India until they were eventually replaced with concrete sleepers.

These are just my opinion,

Thanks,

That's very interesting, and thanks to all for the various info !

 

Does anyone have more info about steel crossties used in the USA? I've never seen them here.

 

Wikipedia has this pic of sleep sleepers that were used on the old North Australia Railway (42" gauge). The caption says they are marked "1885 KRUPP P & PC R".

Relevant info from 

https://en.wikipedia.org/wiki/Railroad_tie

 

Modern steel ties handle heavy loads, have a proven record of performance in signalised track, and handle adverse track conditions. Of high importance to railroad companies is the fact that steel ties are more economical to install in new construction than creosote-treated wood ties and concrete ties. Steel ties are utilised in nearly all sectors of the worldwide railroad systems including heavy-haul, class 1s, regional, shortlines, mining, electrified passenger lines (OHLE) and all manner of industries. Notably, steel ties (bearers) have proven themselves over the last few decades to be advantageous in turnouts (switches) and provide the solution to the ever-growing problem of long timber ties for such use.

 

When insulated to prevent conduction through the ties, steel ties may be used with track circuit based train detection and track integrity systems. Without insulation, steel ties may only be used on lines without block signaling and level crossings or on lines that use other forms of train detection such as axle counters.

Concrete ties have the same problem in derailments. There's something to be said for good old fashioned wood, as long as your Bedouins don't use them for fires.

Steel sleepers (crossties) have been used on the isolated Normanton-Croydon railway in Queensland Australia since 1888. This line is still in service for tourism using vintage railmotors. It has always had relatively light traffic. Photo from internet:

The line was constructed in an unusual manner, with hollow steel sleepers packed with mud to avoid the need for track ballast.[2] This method of construction also meant that the line was not subject to damage during frequent flooding during the wet season,[1] with most of these original sleepers still in place.

Elliot,

I tried to ignore this post for almost a week but I feel compelled to speak up for concrete ties. I grew up around tracks with concrete ties in India & so love them a lot more than wood ties (OK, I hate wood ties), similar to the attitude of the obnoxious sport fans defending their favorite sports team.

Concrete ties by itself have the disadvantage you mentioned of not being convenient to reuse / repair after a derailment but how often do trains derail on tracks having concrete ties? Whenever I read articles on this forum or pictures online of derailments, I almost always try to find what ties were under the tracks. I have seen photos of derailment on tracks with wood ties because the ties deteriorated allowing the rails to roll or the gauge widened or the ties shifted. The only derailments I see on tracks having concrete ties seem to be unrelated to the ties like grade crossing collision or trains passing a signal, at danger.

Concrete ties are expensive & seem to be used in North America where wood ties didn’t work before like the consistently heavily loaded tracks like in the Powder River Coal Basin in WY or for high speed rail where the concrete ties, along with the continuously welded rails & perfectly graded road bed allow smoother rides at higher speeds.

Concrete ties don’t rot like wood ties with age.

Concrete ties don’t use spikes which seem to come loose on wood ties.

Concrete ties can be fabricated in large quantities with dimensions closer to the design dimensions which means less variation from tie to tie.

Concrete ties have the fastening mechanisms like Pandrol e-clip, fastclip or Vossloh’s cast-in built-in not installed on site as in wood ties allowing greater variance in gauge in wood ties.

Concrete ties are much heavier (610 to 882 lb / tie) vs 200 lbs for wood tie which prevents concrete ties from shifting as much as the wood ties.

 

These are just my opinion.

Thanks,

Naveen Rajan

Here is more on the benefits of steel ties:

http://www.narstco.com/benefits.html

The first line mentions:

The estimated life of a steel tie is presently set at 50 years.

I didn't really see anything that mentions rust as an issue. Wouldn't rust be a problem in especially very humid climates?

Tom 

I suspect rust wouldn't be any more of an issue than it is for regular rails, tie plates, rail fastenings, etc.

It's interesting to note that modern steel ties don't need tie plates and the cant for the rails is built in to the shape of the steel crosstie. But the rails would need to be insulated from the steel ties for conventional signalling systems.

The banner photo on their web site shows steel ties with different profiles in the same track. Apparently they make various types with different ratings for different applications.

Always found this topic interesting...Ace thanks for the original post.

Here is a link for an installation of NARSTCO Steel Railroad Ties for the UP at Joliet, Il.

https://youtu.be/7CMWPpg8v7k 

Note that the ties are laid out, then the rails, initially all on no ballast and then the tamper comes along and scoops the ballast and inserts it under the "pods"/ties which were hollow and at that point, filled with the ballast.
