* Transport problems seen partly to blame
* Feb industry order bookings rise 12.5 percent yr/yr

STOCKHOLM, April 9 (Reuters) - Swedish industrial output eased again in February, raising questions about how fast strong business and consumer sentiment gauges will feed into a solid upturn for the Nordic country's hard-hit manufacturers.
Swedish industrial production dipped 0.8 percent in February from January and fell 1.5 percent from a year earlier, statistics office SCB said in a statement on Friday.
Output in January was also revised down to show a 0.6 percent decline year on year versus a previous 0.2 percent decline. The month-on-month rise was revised to 1.2 percent from the orginally reported 1.6 percent.
"It's a negative surprise, and it puts some pressure on our forecasts for Q1 GDP," Danske analyst Stefan Mellin said.
The Swedish economy suffered its steepest fall since World War Two last year as the global financial crisis wiped out demand for the products of top-flight manufacturers such as world number two truck maker Volvo.
The downturn was eased by massive stimulus by governments and central banks and recent quarters have seen gauges of business and consumer sentiment rise steadily, but these have yet to yield a firm recovery.
"Industrial production continues to defy what we are seeing in the leading indicator data. It is a mystery," said Elisabet Kopelman, analyst at SEB.
"Our basic view is that the development seen in the leading indicators should be visible in the real data in time. This does not alter our view of the overall economy," she added.
Sweden's railway system was hit by massive delays and cancellations in February as harsh winter conditions left trains standing across the country. This was likely to have weighed on output in the month, Nordea analyst Torbjorn Isaksson said.
Order bookings for the industrial sector continued to rise, climbing 12.5 percent year on year compared to a revised 3.9 percent gain in the previous month.
"Order bookings for the export market are up 20 percent compared with one year earlier and that suggests there is a recovery at the door for industry," Isaksson said.
