PIKO pays tribute to this historical value in the H0 scale model. The result is a model that perfectly captures the character of the prototype. Typical attributes of the PIKO Expert models can also be found on the ET21: Finely engraved and extremely plastic-looking fan grilles, precisely openworked bogie panels, and extremely filigree roof equipment. These features are complemented by an absolutely prototypical paint scheme and equally accurate printing. The model is powered by a five-pole PIKO motor with two flywheels. The retrofitting of a digital decoder or a vehicle sound can be easily accomplished thanks to the PluX22 interface and suitable installation space. Almost obligatory is of course the LED lighting in red and white, which changes with the direction of travel.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Piko 51604 &#8211; ET21 Electric loco, PKP, Era III, DC<\/p>\n","protected":false},"featured_media":105250,"template":"","meta":{"_acf_changed":false},"product_brand":[985],"product_cat":[835],"product_tag":[],"class_list":["post-105249","product","type-product","status-publish","has-post-thumbnail","product_brand-piko","product_cat-835","pa_era-iii","pa_gauge-standard-gauge-1435mm","pa_railway-country-pkp","pa_scale-h0-187","pa_system-dc-2rail","first","instock","purchasable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Piko 51604 - ET21 Electric loco, PKP, Era III, DC - eRail - Railway modelling<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.erail.gr\/en\/shop\/piko-51604-et21-electric-loco-pkp-era-iii-dc\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Piko 51604 - ET21 Electric loco, PKP, Era III, DC - eRail - Railway modelling\" \/>\n<meta property=\"og:description\" content=\"Piko 51604 - ET21 Electric loco, PKP, Era III, DC\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.erail.gr\/en\/shop\/piko-51604-et21-electric-loco-pkp-era-iii-dc\/\" \/>\n<meta property=\"og:site_name\" content=\"eRail - Railway modelling\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/erail.gr\/\" \/>\n<meta property=\"article:modified_time\" content=\"2026-02-26T11:15:38+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.erail.gr\/wp-content\/uploads\/2025\/12\/39446_51604.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"1720\" \/>\n\t<meta property=\"og:image:height\" content=\"1720\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data1\" content=\"1 minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/\",\"url\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/\",\"name\":\"Piko 51604 - ET21 Electric loco, PKP, Era III, DC - eRail - Railway modelling\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/#primaryimage\"},\"image\":{\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/www.erail.gr\\\/wp-content\\\/uploads\\\/2025\\\/12\\\/39446_51604.jpg\",\"datePublished\":\"2025-12-01T14:56:59+00:00\",\"dateModified\":\"2026-02-26T11:15:38+00:00\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"en-US\",\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/#primaryimage\",\"url\":\"https:\\\/\\\/www.erail.gr\\\/wp-content\\\/uploads\\\/2025\\\/12\\\/39446_51604.jpg\",\"contentUrl\":\"https:\\\/\\\/www.erail.gr\\\/wp-content\\\/uploads\\\/2025\\\/12\\\/39446_51604.jpg\",\"width\":1720,\"height\":1720},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/piko-51604-et21-electric-loco-pkp-era-iii-dc\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Shop\",\"item\":\"https:\\\/\\\/www.erail.gr\\\/en\\\/shop\\\/\"},{\"@type\":\"ListItem\",\"position\":3,\"name\":\"Piko 51604 &#8211;
