A small tram like the one previously quoted can climb high grades due to a higher power to weight ratio. I believe that most mainline rail is designed for a 1% grade but a passenger rail line run on a 3.5% grade. A 3.5% grade would require approaches of approximately 1.5km which is long but not unreasonable.

I assume that since the LINT can go up to 180km/h, it has a high power-weight ratio. And that it's high enough to make it over the bridge.
