The MPL signal system has seen a few changes this week. Most obvious is the new intermediate signal at the base of the climb to Timber Creek, for northward movements through the “Mogollon” block. Meanwhile, the absolute signal at the Ogden tunnel portal has been removed – this means movement through staging is governed by signals at Control Point North Hill Valley.

Our “open house” mode has also been reprogrammed. The signals should no longer lock up at Stop when running bidirectionally without a dispatcher.
