ALIAS(TRN2, 101)
ALIAS(SIG1_TRN1_APP, 30)
ALIAS(SIG2_TRN2_GO, 33)
ALIAS(SIG3_STN_EX, 36)

PIN_TURNOUT(TRN1, 22, "Station entry")
PIN_TURNOUT(TRN2, 23, "Station exit")
SIGNAL(SIG1_TRN1_APP, 31, 32)
SIGNAL(SIG2_TRN2_GO, 34, 35)
SIGNAL(SIG3_STN_EX, 37, 38)

// Start up with turnouts closed and signals red
