Looks like a track scale. Long way round is over the scale, strait track = no scale.

Scale track. One set of rails goes over the scale and the other set bypasses the scale mechanism.

It's a scale for weighing cars. The bypass is to avoid having super-heavy items, like locomotives, on the scale. :) /CraigMW, Minneapolis

It's a scale track. The building at left has the scale read out and the straight track will take you over the scale. The "gauntlet" track out to the left and back is used to bypass the moving portion of the scale.

Could be that one of the pairs of rails is a scale track--engine goes across on other pair to prevent overloading the scale, likely in the building at left.

That is a scale track. It's designed to weigh loaded cars against their tare weight for billing & train information purposes. Normal operation is straight rail past the scale. The diverging rail towards the scale house is the scale & cars would be pulled or shoved that way for weighing.

Can it be a scale, where the loco goes on one side and cars go on the other ?

I would hazard 2 guesses there seems to be a break on the 3 left rails so it for swapping out trucks, or something as simple as a scale with the building next to it housing the scales. This would somewhat isolate the scale mechanism from through traffic.

Scale track for weighing railcars.

Scales. You use the rails going left for weighing cars and the straight track for bypassing scales (to avoid wear and tear on scales).

It's a track scale. One way thru scales the car and the bypass does not. Scales typically have a rating and locomotives and such can break the scale.

The track to the left is a scale track, used to weigh cars.

The diversion to the left carries cars over a scale for weighing. The building on the left is the scale house.

Bypass for the scale. The "live" (scale) rails go straight, while the bypass goes around it. This way you don't have the weight of the locomotive on the scale.

Scale track. It is to get a accurate weight of the cars.

I'm going to go out on a limb and say, based on the prior responses, it's a scale track. :-)

Whelp, I guess I know where to go if I have a question on a RR anomaly...

Difficult to tell from the photo and possible telephoto distortion if the scale is large enough to weigh a car complete or if it is so small as to only weigh one truck at a time.
