@Nyamo Kurosawa: In real life, class G (GI/1E) operates in 4-car sets (usually 2 sets coupled together to form a double (8-car) unit on U1, U2 and U3 or operate in its own on the U4, similar to other small profile trains (like Classes HK, IK and JK) except class A3 (which being configured in married pairs). I would like to ask whether we should said 2 cars per unit (married pairs) or 4 cars per unit for this type? Hlfxcuc (talk) 20:29, 18 December 2025 (UTC)[reply]
