It runs a train back and forth with realistic acceleration and deceleration, and also supports optional station stops for more varied and lifelike operation.\u003c\/p\u003e\n\u003cp data-start=\"530\" data-end=\"871\"\u003eWhen the locomotive reaches the end of the line, the module detects it entering an isolated section of track, slows it to a standstill, waits for a set period, then accelerates it away in the opposite direction. The same process repeats at the other end, allowing fully automatic shuttle operation without the need for a separate controller.\u003c\/p\u003e\n\u003cp data-start=\"873\" data-end=\"1208\"\u003eOne or more intermediate station stops can also be added. As the train enters a station section, it slows smoothly to a stop, waits for the programmed time, then departs again in the same direction. This makes the SAS2-BR ideal for branch lines, end to end shuttle services, and other layouts where realistic train movement is desired.\u003c\/p\u003e\n\u003cp data-start=\"1210\" data-end=\"1398\"\u003eThe module includes adjustable train speed and waiting time settings as standard, with additional programmable options available for acceleration, deceleration, and fixed or random delays.\u003c\/p\u003e\n\u003chr data-end=\"921\" data-start=\"918\"\u003e\n\u003ch3 data-end=\"938\" data-start=\"923\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eAutomatically operates a DC locomotive back and forth along a single track section.\u003cbr data-start=\"1498\" data-end=\"1501\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eOptional station stop function allows the train to pause at one or more intermediate stations.\u003cbr data-start=\"1595\" data-end=\"1598\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eBuilt in DC throttle removes the need for a separate speed controller.\u003cbr data-start=\"1668\" data-end=\"1671\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eSmooth acceleration and deceleration for more realistic train movement.\u003cbr data-start=\"1742\" data-end=\"1745\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eAdjustable waiting times using simple on board controls.\u003cbr data-start=\"1801\" data-end=\"1804\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eAdditional programmable settings for speed behaviour, stop durations, and fixed or random delays.\u003cbr data-start=\"1901\" data-end=\"1904\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eSuitable for OO, HO and smaller locomotives.\u003cbr data-start=\"1948\" data-end=\"1951\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eQuick and easy to connect and set up.\u003cbr data-start=\"1988\" data-end=\"1991\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1431\" data-start=\"940\"\u003eBuilt in short circuit protection for reliable operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"1436\" data-start=\"1433\"\u003e\n\u003ch3 data-end=\"1464\" data-start=\"1438\"\u003eElectrical Requirements\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-end=\"1497\" data-start=\"1466\"\u003e12V DC power supply required.\u003cbr data-start=\"2107\" data-end=\"2110\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1497\" data-start=\"1466\"\u003eRecommended supply rating: at least 0.5A for Z and N gauge, and 1A for OO and HO.\u003cbr data-start=\"2191\" data-end=\"2194\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1497\" data-start=\"1466\"\u003eMaximum traction current: 0.5A.\u003cbr data-start=\"2225\" data-end=\"2228\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1497\" data-start=\"1466\"\u003eCan be powered using either the screw terminals or a 2.1mm centre positive DC jack plug.\u003c\/li\u003e\n\u003cli data-end=\"1497\" data-start=\"1466\"\u003e\n\u003cspan class=\"BZ_Pyq_fadeIn\"\u003eA compatible plug in power supply can be purchased from the BLOCKsignalling website \u003ca href=\"https:\/\/blocksignalling.co.uk\/products\/psu2\" title=\"PSU2\"\u003ehere\u003c\/a\u003e.\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"1502\" data-start=\"1499\"\u003e\n\u003ch3 data-end=\"1530\" data-start=\"1504\"\u003eWiring Diagram\u003c\/h3\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/4009\/9673\/files\/b1_430dfc2c-f2b7-4b48-8016-b4cfbc41ea7e.png?v=1775765940\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/4009\/9673\/files\/b2_99dc9bfa-b92d-4f05-a6f8-2db6facdade1.png?v=1775765947\"\u003e\u003c\/p\u003e\n\u003chr data-end=\"1502\" data-start=\"1499\"\u003e\n\u003ch3 data-end=\"1530\" data-start=\"1504\"\u003eSpeed and Time Adjustments\u003c\/h3\u003e\n\u003cp\u003e\u003cimg\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/4009\/9673\/files\/Screenshot_2026-04-09_211832.png?v=1775765949\"\u003e\u003c\/p\u003e\n\u003chr data-end=\"1502\" data-start=\"1499\"\u003e\n\u003ch3 data-end=\"1530\" data-start=\"1504\"\u003eDocumentation \u0026amp;
